go with a Rage, the material is stiffer and won't stretch as much.
get a F6 2-ply open back with a reinforced scoop collar call Ken Anderson online
Yeah thats what i ended up getting, an F6, but its a single ply shirt.. Im not too big of a fan of a double ply, there a little too rigid for my liking
I just wear under armour, don't see the need for a bench shirt honestly.
