Thanks for all the suggestions guys!
One thing I noticed today when I went out and road is how much I lean on my handlebars, and I think it might be hindering me a lot. I tried to focus on it, and put more weight in my legs, and it seemed like the bike was easier to manuver - should that be true?
I've been downloading videos like a fiend, and just ordered Overend's book. Summer may just be too short this year.
And Re: flipping over the handlebars - I'm sure it'll happen eventually. Not a matter of if, but when, you'll fall, I would imagine.
