As I experienced, material is pretty important for progress, so I tested about 12 foils in the first 1/2 year, as listed here ( http://kitejunkie.com/kite_hydrofoil
) see chapter 6... at bottom of page.
I didn't finished these test reports yet, anyway they would have been in German.
I started with a 2014 Zeeko Makaira Freeride, that's frontwing and pitch stability, but also performance had been great for beginning. Thanks to the very good low speed performance, I never reached angles that high against the wind of much more than 45° again. But after learning 360s and jumping, I wanted to change to a faster and more solid construction. Also if the Zeeko was great for freestyle, doing turns especially in waves felt to stiff in yaw and pitch axis and maybe jumping and torsional forces caused a little repairable crack in the fuselage.
So I found the Levitaz Aspect 3 which is a fast racefoil and one of the static most stable construction I know. I belive it can port times more torsional forces than all other constructions, thanks to a double iron core connection from the strut to the frontwing. It has taken a time to perform same maneuvers on the Aspect 3. But apart of freestyle and close to indestructibility, I now can travel around our lakes with comfortable speeds. Ones reached within 3 hours about 20 km upwind and 20 km downwind nearly 80 km total, some freestyle in the run and average top speeds of more than 40 km/h for over 5 km. Top speeds up to 48 km/h with 62 kg. And in light wind as today I can still stay out with it when all others, also foilkiters, stay on the beach and windsurfers aren't moving visibly anymore
... with just a 9 m Flysurfer Sonic
These days I tried the new Levitaz EXO Board and I was very happy, as the 6,2 kg with 3 straps ( Board naked 2,5 kg) felt great for jumping-boardoffs, much better than my old heavy race-foilboard.
