need to do some tuning with the smaller kit, cant get comfy for now the third session on it. Was better today with the bigger fin, changed down to the s type 32cm and couldnt keep my speed up through the chop. Did 1000m at 30knots.......1500 at 29 knots but could not keep it going at the far end, tried a nmi out through the middle and was averaging 29 for 1000m then took off
