Bob,
I'm not going to get in too deep here into how to do snaps, there's already been a ton of advice, I don't think I could offer anything of magic that will solve issues. I will tell you that I do leed snaps on an upline with oposite rudder, just a small amount, not enought to change headings, but enough to "load" the inside of the fuse (as related to the snap direction).

As for speed, don't assume because you like to fly slow you'll be scored poorly. Not sure if things used to be different in the NW but there are lot's of guys who fly really slow, some fly faster, but I think it's actually less common than you may think. Once noise and overflight came to the forefront of peoples attention, more effort has been focused on controling those two factors, thus slower speeds.

I see your from Camano Island. I live in the Arlington, Smokey Point area. I fly in Snohomish, if you'd like to hook up and do some flying, let me know. We have a large group of IMAC guys at the Cascade field, so there are plenty of guys to practice with. A couple of us fly in Lyman from time to time as well.

Glad to hear your coming back to IMAC. I look forward to flying with you, let me know if I can do anything for you.
