I found TRC wheels to be a bit on the wobble side as well. I personally love Jaco tires and really would prefer to run their rubber only, but their wheels are not something I like, so I use Yokomo black wheels (the ones you see on masami's rear tires at the worlds), they are very strong, yet light and best of all, round and not brittle like Jaco wheels.
What also bothers me about TRC wheels is that they have a different offset.
