Thanks for all your comments I'm definitely cautious with the blind curves on descents because I'd like to be racing my bike in the years to come. My parents continually remind me about the dangers of cycling, speed, and cars, and I try to be conservative with all of the above.

I'm practicing 3-4x a week on small sections of a mountain behind my house in the afternoon when basically no cars are coming up or down. I can see how with countersteering I need to put more weight on my outside foot, as Oakleaf said, and how the inside hand should push slightly toward the inside of the turn. Today, at slower speeds, I saw how I could lean my whole bike over toward the inside of the turn, with my body remaining more straight, by weighting the opposite hand and foot as said. I have felt the effects of countersteering with weighting my inside hand at the velodrome, when I'm coming around the turns at the as close as possible to the inner edge. I'm trying to apply this to turns in the hills, but at the track I'm pedaling, and on descents I'm working more with gravity.

I'm confused about what Oakleaf said about using more front brake. I understand it has more power than the back, but might it also throw me over the handlebars if I try to use it more than the back? Should I just tap it or what? I know my most stable braking is when I have my feet level, I'm off the seat and push my weight far back, and my hands are in the drops with my arms almost locked out. But I save this for emergency when I'm going very straight and fast.

Also I'm going to look into resources for motorcyclists, because I'd like to know more about choosing a line and such. thanks for the idea!
