based on what? if u slam it, most likely any cf hood will crack. i have look at both cf hoods and say both r very good in craftsmanship. i seen the more recent VIS hoods and they have rolled edges and have a nice weave to em. the FI hoods r also nice but sometimes highly overpriced. shop around and a few members here have had both. ask cruial v2.2, he has the VIS one.
