There is no one who can make the decision for you - but there is a huge amount of general information out there. I personally spent 3 months researching. Back in the late 90s there weren't as many resources, blogs, etc, but I did spend a lot of time on
A Woman's Guide to Breast Augmentation and Breast Implants | ImplantInfo. I did the research. They gave recommendations for how to locate and research doctors, the details to look for and the questions to ask. I reviewed the several in my area, reviewed their medical credentials as well as any record of malpractice. I then went to 3 different ones for consults - this helps to get an idea of the going rates, how each doctor presents what they particularly do, gives you a chance to ask questions and even see how you interact w/ the doc. One of the 3 I went to I immediately didn't like - I don't recall the reason, but I do remember just not feeling like he was easy to talk to or that he was really listening to me. I also made a point to avoid those who were "cheaper" and their book of before / afters consisted of what looked like a lot of "dancers". Back then there were fewer who probably did work on gym people because Physique Competition was much smaller and implants were still a bit of a "hollywood thing'. That has changed significantly so you will probably find many who have worked on at least a few competitors / gym people and will be able to answer questions about training.
In your case, you'd also want to ask specific questions about experience working w/ female athletes, particularly weight lifters. Even better if they are gymrats themselves and "get it". You can further ask what they would recommend for your particular body, lifestyle and needs. I found the doctors I went to favored a particular approach - in fact it was never asked if I wanted "overs" or "unders" - this is just what he did. In terms of recovery, he didn't mention anything about the "massaging" and didn't call out anything particular (training-wise) to do or not do. The only thing he really said was to not lift my arms above my elbows for the first couple weeks, and not above my shoulders for the first month. This was to allow the implants to heal and to reduce chance of capsular contracture. I followed this religiously because I'd seen one girl at my gym who ignored that advice and had implants that were rock hard and looked pretty when you saw the actual implant.
If you know anyone in your gym or who you lift with who has had them, definitely ask them questions and if they have any recommendations for a doctor. I had been thinking about getting a redo w/ silicone for a number of years, but didn't actually do it until I had a friend who I trusted implicitly and was a heavy lifter, recommended one. I did the same research on this guy before I went in for the consult. I was very happy with him and the results.
The other thing I liked about implantinfo.doc was back then they had a forum and a live chat - there were a lot of women who were also scheduled for the surgery or recently completed the surgery who posted so you could ask them questions or look at their updates as they went thru the whole process. Sometimes there's no better insight than people's comments as they go thru the process.
My personal experience - for my first surgery - I remember they were very good and I was very comfortable going into surgery and even remember as I fell asleep w/ the anesthesia. I woke up later that day in their recovery room - it didn't really "hurt" but I do remember coming out of the sleep literally feeling like an elephant was sitting on my chest. After a day that stopped. Then the issues were how hard it was to get in & out bed to go to the bathroom or up & down the stairs because of how tight my chest felt. I ended up sleeping in a recliner chair in my living room on my first floor for another 3-4 days. I was off all the pain killers within about 5-6 days and back to work a week later. The most annoying part of recovery was the random shooting pains I'd get where nerves were regenerating. I also had a hard time driving when I had to look behind me to back up. Anything involving rotation of my torso hurt some. A month later I was out in clubs w/ no bra on jumping around all night. It rocked! Training-wise - I was back doing cardio after 3-4 weeks - again the biggest issue was just tightness and random shooting pains when I suddenly moved my torso left or right. I started training as well but stayed away from back or chest for a while. Then I started prep for my first show about 3 months later. This obviously involved chest - it took a while to get into it comfortably because I was dealing w/ breaking up the scar tissue and also the random muscle spasms I would get while the pecs were engaging. That just took a while to get used to, and eventually it just became a non-issue.
None of this stuff would be an issue if you get "overs". And additionally these days the recovery time is significantly shorter, and I'd venture the pain is significantly less because of improved methods & technology. And I imagine there are even more options than just "unders" and "overs". If we were talking about "pain" levels for this surgery, I wouldn't count it as all that much of a big deal anymore - nothing like it used to be.
As I said, I would do the research to get a better understanding of what is available. Get on implantinfo.com or another is implantforum.com to talk to real people getting them done - also a great time to ask questions when many of these people are still asking their own doctors practical questions. On these sites you can also often get a good idea of what the going rates are in your area so would also be able to guess if someone is charging too much or too little for a good job. And then pick a couple docs to schedule consults. Back when I did it, the consults were typically free. I hear more recently they might not be - or the cost would go towards the price of the surgery if you chose that doctor, so money for the consults might be a consideration - but still the best info you can get is to talk to a couple docs, share your concerns and get their response in terms of what they might recommend for you both for the surgery type as well as training guidance afterwards / going forward.
The only person I've ever heard of having a blow out was my colorist back in California - she was a power lifter and had been benching in a shirt - obviously that's a huge amount of pressure on an implant, but I personally have never had any issues at all.
