I have 3 different masks, i have vforce grillz, jt proflex, and jt spec 8. I prefer my grillz the most of the 3, i have owned i4s and i didnt like them at all, they were way to small for my face so i sold them and bought my proflexs, but i would recommend anything from the vforce line. all their masks are great, also try the empire events, they r good as well
