Currently I'll do DB flys followed DB bench press...I need to look at some videos and actually study how to do flys properly, as almost every time i've seen videos on them they look exactly like benchpress just with your hands facing the other way!
I'll figure it out soon hopefully...It probably is something as simple as I'm not 'trying' to tense the muscles there or something.
Yeah could be, I find that it does take a while before exercises 'lock in'. One tip would be to visualise in your mind the muscles you are targetting tensing as you do the rep. The fly should feel very different to the press, personally I find the fly hits much more as it really squeezes the pec when done right.
This vid is pretty good for checking proper form:
