Actually, Silent Spinners are considered unacceptable for hedgies.
Besides falling apart and falling on hedgies, the crevice in the middle is a toe and nail trap that can cause your hedgie to rip out their nails...
Flying saucers is a bit undecided, but popular. I personally love mine and my hedgie uses his well. It's also very easy to clean.
There are other wheels to consider, like comfort wheels, and Reaper's Cake Walks(which comes highly recommended)
