10:30 0.25 hour Wind: S 22/28 kts
Board: JP Freestyle Wave 84 Pro - K4 Rocket 18,5cm/K4 Rocket 2x12cm
Sail: North Ice 4.7 - North Gold(a) 400cm - Aeron V-Grip 160-210
  (machine translated in 2023) First time with the K4 Rocket 18.5 (now the whole set).
Bit too little grip, really can't put pressure on rear foot. If the fins in the chop come loose, you have to be very careful otherwise the board will immediately lie crosswise in the water.
Board is low in the water and sails predictably like a skateboard. It is difficult to jump if you cannot put pressure on the fins for the outlet.
Another test in real waves.

10:45 0.5 hour Wind: S 22/28 kts
Board: JP Freestyle Wave 84 Pro - MFC Freewave 22,5cm/K4 Rocket 2x12cm
Sail: North Ice 4.7 - North Gold(a) 400cm - Aeron V-Grip 160-210
  (machine translated in 2023) So, that immediately felt good, plenty of grip, control, ran height. Even in the harshest gusts no problems. All short turns on the chop: never slip. Sail was on the large side, but still doable with maximum trim. Never any problems.

11:15 0.5 hour Wind: S 20/28 kts
Board: JP Freestyle Wave 84 Pro - TFC Wave 19cm/K4 Rocket 2x12cm
Sail: North Ice 4.7 - North Gold(a) 400cm - Aeron V-Grip 160-210
  (machine translated in 2023) The TFC 19cm is between the K4 18.5cm and the MFC 22.5cm. More rest, board lower in the water, but still just a little slippery. Bit carefully through the chop. But in the corners already very predictable. A bit tricky to walk.
Test again in real waves.

11:45 0.5 hour Wind: S 20/26 kts
Board: JP Freestyle Wave 84 Pro - MFC K-one 23cm/JP Side Wave 2x10cm
Sail: North Ice 4.7 - North Gold(a) 400cm - Aeron V-Grip 160-210
  (machine translated in 2023) 10cm thrusters with the K-one 23cm also works very well, the board runs clearly looser than with the 12cm thrusters, good to know that the board can tune well in how loose the board is on the water. Furthermore, the set sailed wonderfully, grip was still very good and sail also felt very good.

12:15 0.25 hour Wind: S 16/25 kts
Board: JP Freestyle Wave 84 Pro - Select Wave Warrior 24cm
Sail: North Ice 4.7 - North Gold(a) 400cm - Aeron V-Grip 160-210
  (machine translated in 2023) Just tested single fin, wind unfortunately already decreased. Board is single fin clearly faster, lies higher on the water, which sometimes gives more rest because you go over the chop, but because of the speed sometimes more difficult. Still runs very easily, but less grip in the corners.
