Cool... they seem like they would fit tighter on a pro-link since they are not already threaded. I've had probelms with a few RCL links being looser on the link that I would prefer. Is the plastic the same stuff or is it wearing better / staying tighter than the RCL links do?

BTW... it sucks not having a LHS so I can look at simple stuff like this. I have to mail order EVERYTHING and I don't want to build my own hobby shop just trying to get a visual on all these items.
