Back to back test;
Slingshot Infinity 84 wing in C+ position with 48 rear wing, washer under the rear wing to force max lift.
Infinity 76 in B position with 42 rear wing.
Riding the swells in, got foiling in 8-10 knots easily with the 84 and with some pumping with the 76.
The acceleration from the 1m waves drove the 84 wing down, even with the mods I can't get enough weight on my back foot to keep it up.
The 76 is awesome, at speed (about 19 knots) across the wave there's loads of lift, throwing weight far forward like a SUP foiler keeps it nicely in control - and it carves sweet turns on the wave face upwind and DTL.
With more wind I'd use the TIme Code 68 which carves even better turns - but for light winds with waves I reckon the 76 is the go.
Crazy fun

Have you ever tried the 76 cm wing with the 48 cm stabiliser? If so how does it compare with the 42 cm stabiliser and did you have to alter mast position from position B?

No, but I'll give it another try.
The 42 rear wing might be easier to push down with my back leg, to maintain height when accelerating on a wave. I don't think I'll use a shim.
