i use a grip a tiny bit narrower than shoulder width for CGBP but if not done it for ages
gladiator you have crazy strong shoulder pressing strength and dipping strength man! I wish my shoulders were that strong, shoulder strength is probably my weak point right now. I know its my shoulders too because if I concentrate on power my military presses are hard for the first half of the ROM then my tri;s come in and snap straighty throught to lockout, the hardest part for me is always from when the bar comes is at about eye level and trying to get it above my forehead is the hardest part, then if can get it higher than my forehead the lockout is easy. I think pushing the weight on weighted dips and not leaning forward so far made the biggest differance to my tri strength. Also makign big improvements on my bench with a pretty narrow grip helped alot too
