Day 2 of comp and 3 full on races all day in windy conditions. The JP 55 felt great for me on the 6.4 and my speeds were competitive. I did try the JP45 using a slingshot 21 but it was always hard getting back to the start of the run. The run up to the start was very gusty due to a small cliff (aparently similar to Kapathos) which meant small kit was hard work.
