Only get the Fasen if you're not sketchy and you don't ride alot of flyout
AOS v2s are pretty weak and I've seen lots of shit happen to them but if you don't go very hard on decks and you want a lightwheight deck thats good for grinds get the AOS v2
V2is are pretty strong and lighter and better for grinds than the AOS V2
All the decks are lightwheight and good for grinds
If you want something cheap, strong, light and good for grinds and flippy whippy tricks get v2i
If you want something slightly more expensive, not to strong and good for grinds and flippy whippy tricks get AOS v2
If you want something pretty expensive, that won't last if you're sketchy or a flyout whore, good for grinds and flippy whippy tricks get the Fasen
But really choose a deck with the perfect specs for you, like perfect width, length, hta, weight etc
