Even if you don't feel that fat but know you have a layer over the abs then do as ExLe says for sure. I started 2 bulks without shedding that fat layer and it definitely haunted me. I'm 5'10 and was up to 81kg in July. I'm now teetering around 72kg and I still have a thin layer left on the abs. Looks like I need to get down to 70kg to see it gone and I haven't seen that weight since my early 20s (I'm now 39). The initial cut to 75kg was easy then I met a huge resistance barrier that I finally broke. I was starting to doubt I could get lower than 74kg.
After I hit 70kg hopefully end of November and I'm feeling thinner skin over the abs I'm going on a 6 month bulk until the start of next summer. Then cut and maintain July/August. I'm thinking around 1.5kg per month bulk should put on some decent lean mass, anymore and you'll be putting on more fat than you want.
So yea, cut like mad so you're starting your bulk with a clean canvas. You'll be suprised at how much you have to cut to get to 10% BF. I almost quit at 76, 74 and 72 as I'm feeling super small and but I'm on a mission and I know the bulk will be more satisfying.
Diet will be most important, cardio certainly won't hurt. I've had 2 groin injuries over this monster cut (kickboxing injuries) that have sidelined my cardio for 6 weeks total but I've still been able to lose weight by a calorie deficit diet. And I do like to binge drink twice a month and eat pizza. Just gotta be super strict with yourself 6 days out of 7.
