Yeah... I would describe the steering as "squirrelly" under spin. It would be nice to have some lee helm to balance it a little more. Just so touchy. If I had an easy answer that wouldn't screw with the nice neutral helm up wind, I would do something about it.
It is a complete BLAST though sailing solo with the spin. I have to lean WAY back in any significant chop though or I will bury it. I haven't pitchpoled under spin though (yet).
When I go over solo with the spin up it is usually due to gybing (thought it does help to let the trav out some when you come around) or when first getting out on the wire and I accidentaly turn town and I fly away from the boat and pull it over on top of me <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
