Thanks...I was thinking that my lats would be my biggest hinderance/weakest link for benching this way...I never even thought about the tris being the first hurdle. Looks like I've got some work to do on them.
I remember about a year ago talking to the manager of personal training at Bally's (not even a regular personal trainer, the guy that trains the personal trainers there) and we were talking about benching. It was back when I had a cheap membership to the gym and he was giving me a free preview of what members get if they pay for personal training sessions (which I think averaged about 50 bucks an hour). This was right around the time I first found this site and was talking to him about how I had just read an article that talks about benching like this (elbows in, driving it from the lower chest/upper abs, etc). He scoffed and said "I don't feel that in my chest at all. You need to keep your elbows out." He then proceded to teach me how to do a deadlift, by saying "bend down and pick the weight up." That was it. Nothing about posture, grip, etc. It wasn't even because he was I was just getting a free preview...I knew a couple of the trainers there, and this is how he trained them to train people that paid to get one on one time with a trainer. I'm glad I wasn't paying him for this session he gave me.
I already learned my lesson to trust what I find here in the mag and forum over anything else, and I feel thankful that I found this place after some of the things I've been told/taught at other sources...it's just scary that so many people actually pay to be trained by so many trainers that are misinformed, confused, and sometimes just wrong.
