Re: high speed wobble
You didn't mention anything but I would think that if it was something with the front end, you would have really felt it in the handlebars. Did the handlebars vibrate, wobble or feel unstable in any way or was it more something you felt through the seat/frame? I'm no expert, just trying to throw out some ideas.
