I usually shy very much away from using any CC forum thread to advertise, unless it's a specific recruitment thread.
In the nicest way possible I will make an exception:)
1. By all means do read the well renowned Pinhunters site:
2. By all means do refer to your clubs website FAQs, which covers off a real simple way (without checking I just say that and so no comparison as to which is best, equal or not etc)..).......
Simple suits me and I nwas good enough for the 200 and below credit RGs I sometimes annoyed real good players in. Plenty of vids showing it all in play and working if that helps. I would add, include club mapping in any research, and the club coach will be more than happy to help out too as a follow up / whenever as will the CC forum (in addition to these very good forums of course).
Cheers
