Re: short -20db barrel pad
yeah, you're not gonna find anything that is a barrel that is much shorter than the standard switchcraft. i concur with silas that if you want a more 'strain-proof' pad, just make one with a jumper that has the resistors in one of the connectors.
i do feel that plugging a barrel directly into any piece of equipment is asking for trouble, at least from a strain relief aspect. i had a bit of a discussion on this forum i believe about my strongly held belief that one piece xlr-1/4" male adaptors should be banned because of the issue of having that huge connector hanging off a piece of gear. this is the same issue. i've always just opted to put a short xlr jumper inline. maybe i'm paranoid, but a little paranoia has served me well over the years...
