Just landed a new slalom fuselage, the 105+ from starboard

I've paired it to a 225cm2 -2? "Thin" rear wing

and trioed a 550cm2 front wing.
The wing shapes and profiles are very similar, it's like SB engineers just applied an x% magnification to the cad drawing!
I haven't had enough time to really push this limits of the foil setup yet, but initial impression is that the 550 does indeed need more speed to fly. I'd say minimum speed on my 900 is about 10kts, 800 is around 12kts and the 550 does't like going below 15kts.
Control of altitude requires more back foot pressure, at least with the rear wing on a zero shim, so -2 degrees.
The combination makes air-gybes a bit harder, but then it makes 'planning' gybes easier :)
