Not sure if you are a member of Den of Angels or not, but here is the info from a "What Fits" thread they have there. There are pictures, but they weren't linked with copy/pasting(that's what the X's are), so if there are any you really want to see, let me know, and I'll add the links.
All this info comes from the totally awesome people from the BBB/RS thread at DOA.
