I fly fish quite a bit so I usually keep my rod tube strapped onto the side. One strap probably would have been OK, but figured a little extra security there couldn't hurt. When not fly fishing, I will just use it for a little more compression. I hope you will post pics of your Catalyst, the pale green sounds interesting. Are you seam taping yourself or ULA?
Derrick - It's Med waist/Long torso. ULA's measurements used to be a little odd for my size, but now they seem spot on.
