I totally agree. It doesn't make any difference what the one the OP has is, because since it has smooth sides now, she has several options to attach. Personally, I would not drill or add any studs and just use the 72-up adhesive style, but if one didn't want to do that, studs is definitely better than drilling holes, so thanks for pointing that out!
Just for completeness, I'll post pics in a few, have a screaming child right now! :)
