So I ran into a problem a few days ago with wheel alignment. A week ago I noticed my real wheel was spinning with an eliptical orbit, or side to side by up to an inch. As opposed to regulary just spinning in place. I went to the bike store to tighten it, looked fine then did a thirty mile ride and found it wobbling just a bit. Then on another ride today i hit a pothole(covered with leaves) and it started to wobble more.

Is this a sign of crap reparing or am I slowly going to have to replace spokes until I get a new wheel? It is annoying so any imput would be appreciated. That said I am also on the husky side at 6'4 260 lbs, but swam Division I at a weight of 210 and was nothing but bones and shoulders.
