Cassandra - I believe you are on the lighter side weight-wise (as am I). Is there a difference in tires with relation to lighter/heavier riders? Which model do you use?

I think I am more concerned w/ speed right now - than flats - though that could be b/c I've never suffered a flat 'knock on wood' and been stuck somewhere. I definitely plan on practicing flat changing, if I can do it on my car, I can do it on my bike. Or atleast follow the directions to the best of my ability?
