| I try to improve my serial fin (JP freerace 50cm) and I wonder, which length I need - I guess you all have a lot experience there? My board: 135l JP Freerace. Sail North R-Type 9.5. Now I don't know, which length I should choose for the fin: 51? 49? 47? The new 2007 Freerace (now called Supersport) comes with a 46 (!) standard fin - 4 cm less than the 2005 model. What do you suggest for maximum speed on this equipment? Thanks a lot from a speed novice! Norbert |  | | |
