I think it's great that you see alot of peopel woh've trained at westside have now modified the program so much it doesn't even look like westsid eanymore. I'm thinking specifically of Jiw W and Mike R, from reading their logs on Elite.
Personally, I've stolen a few things from Louie and put it all together to find something that's working incredibly well for me. I do one "main" exercise on my bench day, but it's not a max effort one, it might be 3x5 or 1x5, I try to improve the weight each week and change it every 2 or 3.
I follow wth either tri's or chest, then shoulders, back, pushdowns. THen there's eiher a second day with an emphasis on speed or heavy shoudler work. Close enough to the basic template, but so bastardized it would be wrond to call it such.
Everything works, but nothing works forever is a really great way to sum it up.
