If you aren't cycling and are benching over 400, you've got much better genetics than I do.
I keep things simple, and low volume. Right now because of my shoulders I have been doing almost exclusively only close grip benches, it still gives me enough of a chest workout. Glen Chabot claimed to only do close grip benches every 2 weeks and no normal benching until close to meet time.
My bones and muscles start to hurt with high volume stuff if I am doing heavy weights, so I have to limit things. I try this and that until I find what I like, and occasinally I will tweak something based on what someone else does (I killed a lot of shoulder work thanks to PB). I am going to pick up one of the Metal Militia training DVDs to see how they deal with shoulders, and everything else.
I have a training log online I can PM you, its not very exciting but its about over a years worth of workouts.
