Don't have the experience of many on here. But I dumped GMs from my 5/3/1. I added power shrugs and love them. I've never had an exercise hammer my traps so good. I get more ham work on squat day, I squat, leg press, then leg curls for hams. So you could always add those in somewhere, or SLDL. Just a thought, hope your back heals quick big man!
