PS There is a really good Regional section in UKGSer, who you could tap for local knowledge, rather than limiting yourself to the rather narrow area of 1200 WC riders (most of whom stay indoors in the SE of this fair land) whose main area of expertise is tuning from a hill top.
PPS Blimey, you have asked the same question in the pub as well. You'll be swimming in a ocean of confusion soon. Though you will have seen you do get more replies there, even if some are just some old fart requoting the pictures of some bod's MX5 interior he's attacked with fake carbon.
