Alright I went through and changed a few things. Mostly a rep structure change. Also Always start with bench, squat, and deadlift on those days. No need to do lat pulls, leg press, etc. before doing the big compounds. Remember you are doing powerlifting not bodybuilding so you don't need hypertrophy specific work like pre-exhausting. Another change was to deads, I think three heavy sets of deads is a lot better for building power than 5x5. Also you may need to think of doing a multi-week taper in order to phase train to peak at your desired contest. Otherwise just keep your diet tight and work hard.
