2004-2005 very similar
2006-2009 also very similar (to each other) and quite different to the earlier years.
Stick with RRD, as far as FSW's go they seem to win all the magazine reviews

I will have a 2006 101L in really good nick for sale at start of next season if you can wait.
If it blows on Tues next week I'll be at Dutchies and you can have a sail on it.
