I'm on my 3rd... Started off on an old T-Bird, which got me going just fine. Then after many upgrades I got a T-Pro frame and bits.. Now I've got my Zona Zip, and it's awesome. Nothing wrong with Onza at all, the T-Comps break because they're not designed for street, the T-Pro's crack/snap because the Alu is a bit thin, but they're still awesome bikes.
