Hey, I noticed like, two hops that I don't know how to fix.. I was wondering if I loosen all the spokes to start over, should the hop go away? What should I do if I see.. Say, a very tiny wobble, and a small hop in the same spot?

Also, should rims generally be completely centered between the calipers, or do they need adjusting for different wheels? I notice that my rim is closer to the right caliper than my left one.
