Swap to DB's for benching, really helps increase your bar bench. Also after 6 ish weeks in a routine I would change it. Change the reps, sets, split, days, exercises. Gotta keep your body guessing. I would also say that legs is a big day and should all be done at once. I find if I train legs I can rarely hit another body part as I'm so spent (unless its some curls)!!
