After riding in a Troxel for years and hating it every time, I finally broke down and bought a more expensive Tipperary. Wish I'd done it sooner. Looks way better, fits way better, feels way more comfortable.
I love the sportage. It is light, cool and very comfortable. It doesn't give you the bobble head look either. They are a great schooling helmet. Along the same lines is the Ovation. Which I am also a fan of.
