i got the 5.5 from early 2 bed... it's pretty good, but I hate that I don't have a harness or anything, and the 'homemade' harness I have, I still have to wear boxer briefs with.
It's good, and I'm tempted to like, talk to Charles Asher to see if I can send my packy and stp in and see if he can like... rig it up, 'cause the guy from transitional male? whose name slips me, has a way to make a packy and stppacky, but he's keeping it to himself.
