With 91/101/111 masts you’d want you back foot big toe to be behind line of rear holes of mast plate. If you’re using 82/92 or RDB 70/90 masts you should have you back foot big toe in front of the line of rear holes of the mast plate.
If you can’t move the mast any further forward and still have too much back foot pressure (or not enough foil playfulness) - shim stabilizer a bit down. 1mm plastic washer on the front bolt between the stabilizer and the fuselage would do. You can cut out and sand down a pretty shim out of an old credit card
Don’t use shims if you can move mast to an ideal position.
What if there is plenty of mast placement but I want to reduce induced drag from the stabilizer and add more speed and looseness feel?
There is no information about how it is possible to improve performance and glide of the foil just by tuning the incidence angle of rear wing more neutral.
Depending on the foil use and personal preference shims can be used not just for mast and feet placement.
That’s a good point. As far as I know Moses 450 was their only stabilizer with messed up AoA - pointed too much down and it needed such correction to ride it normally.
Otherwise I’d rather be choosing thinner and/or smaller one instead, usually race stabilizers come into picture for that and they improve things more than shimming. What I mean you can shim 483 all you want but good old 425 will be better anyways for more speed and play. Folks riding waves and looking for least yaw stability pick 370 or similar flat stabilizers.
On the opposite side - if I want a wing to go slower, even a freeride wing like 695 or 730, I replace my good old 425 with RDB 310 and it has effect of almost a larger surfier wing. I know Gunnar is not in favor of that view but I tried riding 720 wing with 325 vs 450 stabilizers side by side and difference in take off speed and ease was very much there. As well as overall stability and reversely cruising speed
Ultimately, a monowing gets very smooth not having stabilizer at all - I posted a quick feedback on Hoverglide H4 ridden without stabilizer few years back.
Yet to original question - the 695 is not a race wing, you won’t achieve more speed by reducing AoA of a stabilizer and 399 is racy as it can be, I wouldn’t shim it unless I can’t move the mast
There’s very little official info on most of kiting gear, which leaves room to buy it experiment, post feedback and learn from others who post theirs
