Good topic - been interested in those new big fuses(same size as you puetz).
14m fuse is biggest size kite I own now - feels like that is magic max crossover size where kites have lighter wind power and still can be whipped around. Debating since I can ride the 14m fuse w a light wind board in low teens n if going to the 16/18m would really be worth it.
Have owned old kites every big size up to old elbow destroying naish v4 25m. Last year bought an ozone zephyr n sold it within a week as I hated it- no grunt for a couple of power strokes until got some apparent wind and was easy to buckle the leading edge even on just a fast transition. Slingshot turbine too previous model didn't like it either w downwind truck pull n mushy bar. I have zero interest in a race style of big kite.
