I agree with wallisj. Ive not had much joy with RSC, especially when compared to Cliosport. I sent off my £20, and after about 6 months of E-Mails I received a membership card and letter. I didnt get info about the specific discounts on offer or the rest of my membership pack or access to the members only parts of the website.
Overall Ive found Cliosport looks after its members better and keeps you up to date with new stuff, as well as involving people more over the net such as with the competitions and a website that actually gets updated. (and its loads cheaper!!!!)
