Thanks guys for the help, I really appreciate it. Fortunately Justin has the opportunity to mod the CMRs into one mini XLR so I think I will have him do it for me.
For now I'll wait with the Tinybox and MK41 caps. I tried buying MK41s from "nottingham" in the yard sale, but someone beat me to it. Maybe a sign from above (or something) for me not to spend too much in one go haha.
