Well thats great. Then I would think they would allow straps in competition too. Using straps to me is like wearing a bench shirt while working out or a squat suit. I am more of a guy who really wants to see how strong he can be. I took allot of pride in my forearm strength way back. I still do. It's fine if others like straps I was pointing out what I like or don't like. I just wouldn't use them.
For a one rep max, I understand why they wouldn't allow wraps in a competition. Making the choice not to use them is cool too, just know you hinder your progress due to ego.
Quick example: You can shrug 100lbs. for 10 without straps, and 15 reps with straps. Which is going to yield better gains for traps?
I'd say 15.
