Many thanks for taking the time out to reply.
I've been reading up as much as possible on this and other sites to understand the intricacies of Rep APs. The whole franken and upgrade options are pretty much amazing, and love the way some people have improved on the base quality to get it to such a high standard!
Its very addictive though! I've just purchased a Safari with oem strap, and a Diver with SS strap and black face. Waiting for both to be delivered so very impatiently waiting!
