Have a chat with Will of Kevin at FTR suspension, they are fountains of knowledge when it comes to all things bouncy and are official Ohlins dealers. They have a �150 cashback offer on at the moment on Ohlins shocks...

They'll also cut you a good deal if you gets forks springs and shock together too.
I went in intending to go the Ohlins route, but ended up with Yacugar fork springs and shock, mainly because they're progressive and have a range of springs better suited to my lightish weight. What ever you get it will be built to order and your requirements.
