The wheels have been holding up nicely, one set been through a regional and a few hours of practice, the other set seeing ~20 hours of usage. We're seeing wear in the roller bearing (bushing?) such that the rollers can now wiggle side-to-side. We're concerned that this may be the beginning of the failure mode that was seen on the OLD 6in and 4in wheels, can anyone who used the older wheels confirm or describe the failure?
The 8in. have had the "reinforced" design since last year. So the ones you bought this year have the same reinforcing that the 4's and 6's have. The wiggling is the same thing that we saw and we replaced the wheel before it got any further.
