I transitioned from a nose-hook Blanik L-23 to my CG-hook LS1f, all on aerotow. To be honest, I don't think there is much difference on the CG hook, and I've taken off in some crosswind/gusty conditions. I'm not terribly experienced either. A buddy of mine has a CG hook on his Discus, and he had the same experience when he transitioned. Maybe some gliders are worse about weathervaning than others, but really I don't think it's as big a deal as people make it out to be.
