When we tried the spi and had problems getting it into the snuffer I think the problem was twofold, we didn't have enough wind in the right direction, and we didn't do it fast enough. Maybe we will try with the downhaul in all the holes next time, and do it faster.
The Seal'nGlide stuff seems a little extreme? Not something to use on a regular basis?

I'm the other new stealth owner in Norway btw.
