Some info from a different weight class

188x97kg

:I have Sunova Casey Elite 7.6x23x137l for supfoil and DW supfoil+ very light wind winging, an AK PHazer5.6x27x90l and bought after demoing different boards the SuperK 6.5x22x 92l So for me its minus 5+wetsuit etc. Foils: AFS Pure1100+ Silk1050 and 850, riding strapless, wings from 5.5 to 3m The cheesiest and honest thing I can say is that the board is Super!

The glide/acceleration is phenomenal. As soon as you sit on your knees the board already starts to get going, its way more stable for me as the 5.6 Phazer and the other boards I tried. That wider tail and extra length does wonders.Bonus: when I have a touch down it easily bounches up.I prefer it in surfing although I can imganine that in more wind and small waves the Phazer might feel more agile due less swingweight. So far I haven,t seen conditions like that and it has been more wider turns waves instead of very short close to the pocket kinda riding.
Compared to some other boards, and please keep in mind that I ride strapless, so I have no clue about foot strap positions
AFS Whitebird 6.8x23x115l. The AFS floats me better obviously but I didnt had the feel that it got me quicker in the foil, and in side chop the AFS was harder to balance for me (maybe because of the thicker rails catching wind?
Cab Swift 6.3x20x100l. ...as most women would tell you..2inches make a lot of differences

In this case in stability. I think the Swift is an excellent board and it glides quickly, but in lightwind serious chop it is for me a B#tch to get on.
Sab Torpedo 100l 6.3x19.90: the one that felt the smallest to me. Least swingweight in the nose, most agile feel and it could easily be my highwind board if it was more stable for me 19.9 is just not wide enough and with touch downs in a bottom turn its more eager to suck in/ not to release as the KT.
