Dont get the bungied wings, First off pressure alone will deflat the wing. Second they DO NOT aid in trim, infact it creates more drag.
Third, the the most important, the bungies make it harder to orally inflat your BC.
Plus a small rupture of the wing and its over with w bungie, the bungie force the wing to stay

Dont waste your money. go with a BP and Wing without the bungie and dont let anyone sell you on it ether.
