Something more to throw into tweaking your ride is the rear shim. I've found it helps for keeping lift in the front wings during slower speeds but can take more speed to get up on foil due to more rear drag. Not really an effect when wing'ing but sup'ing yes. I also ran the rear at half the thickness and really liked that the most.

Also I'm finding 1150 ultra short fuselage and 370 rear for me as my session saver or if conditions are clean and I want super long glides. 10 mph and I'm powered. Higher winds I'm still loving the 1000 on a short fuselage and 340 rear.
If I go 860 then I'm on the short fuselage with 390 rear.
