I use the decline all the time. It's grown my traps. Works my should and tri's. It works for me. That's b/c I suck at free bench incline. I cannot do incline. Something is wrong with my physio structure, so to work the upper pectoralis major, tri, anterior delt I use the level bench and the incline chest press. I find the cables and the incline chest press to help my weak sides.
