Sure Derek,
You can use EZ bar curls too. There are many exercises for building large tri's and bi's.
Like SJ said, hammer curls are very good, and I do heavy preacher curls with both dumbells and barbells. Other good ones are concentration dumbell curls. Those are awsome hence the name, you can get great concentrated focus on your bi's. Also keep in mind the various grips... They all build different parts of the tri's and bi's.. inner grip builds outer bi, medium is more center, and outer builds inner bi.
I pick 3 favorite bi exercises and do 5 sets each. I then pick 3 favorite tri excercises and do the same 5 sets each . I set the weights as heavy as I can so I can just barely do 12 reps. (But FIRST IMPORTANT -WARM UP ) Then I add weight each time and next do 10, then 8,6,4. Each adding weight in between. I pretty much follow this with both tris and bi's. After 6 weeks, I rotate and do completely different exercises. I'm hitting heavy right now on hammers, heavy preacher, and concentrations. In addition to doing dips.. Dips are great for your tris. I want to also add a lot of chinups, which helps to build your bicep peak. But if your going to grow evenly, it is important to change your exercises every 6 weeks or so. This way your not just doing the same thing over and over. There are more than just one part of the muscle you have to remember.
Now you ask how long it will take. In my experience..at least natural that is, don't expect to see any serious gains before say 6 months. You will feel stronger, but won't notice a whole lot of gains till after 6 months. Then after 6 months, you continue on a serious role and you will start to notice great changes. The funny thing is most people give up before that.. They work hard for several weeks, maybe a few months, but because they don't notice serious change, they toss in the towel. What they don't realize is they toss in to early.
