Id say inclines are greatly underrated. Most trainees seem to flat bench alot more then they incline, or do very little incline work. I reached a point where I was flat benching more then inclines also, but even at that point I still had a seperate day for them and hit atleast 8 sets on the incline bench alone, then cybex inclines and some additional chest work along with shoulders. Ive always kept a good amount of incline work in my routines. I feel it helps with flat bench strength as well. I definately feel more strain in my upper chest area with the movement as well. Though Ive never gotten my upper chest as thick as Id like, despite repping 315 and hitting 375 on inclines. Perhaps the shape is somewhat "genetic" also. But I believe with enough chest mass the problem will be corrected. I also like the shoulder stress I get from heavy incline presses. Definately one of my favorites.
