I've been working with a 5x5 routine lately and seeing good results. My goals are size and strength and so far the 5x5 routine has given me the best of both worlds. I lift with a controlled eccentric and explosive concentric movement. Usually on the last 2 sets I can only get 2-4 reps. I know this is normal but the bar always gets stuck like 4" off my chest and I feel that if I could get past this sticking point I think I might be able to get 1 or 2 more reps.

Do you think adding a DE bench day would benefit my 5x5 routine? Im not a powerlifter or anything but to me it seems logical that if a little bar speed could get me 1-3 more reps on my last sets I would see better results.
