The T-Hall would be my choice over the AR7 but the Alpha 1 is above both. The race base is amazing if waxed or if your like me and wax it every 40 times its still much better than the AR7, Halo, and T-Halls base. The elf shoe makes spins on and out of rails/boxes so much easier and you wont catch as much because of the rocker in the tip and tail. The stiffness is the same as the AR7 so you can stomp big landings. The rocker makes them decent in powder(much better than AR7 or T-halls) and the turn radius is super low(12,14, and 15.5m), which make shutting down speed in tight lines/ trees easy. Also it makes carving into jumps easier, and makes switch take offs much easier because you dont get caught up on the lip. Also they are better in bumps because they have a tiny waist and the rocker helps a lot. There is not another ski even close to the Alpha 1. Corks, rodeos, and flips are also easier because you can roll onto/off of the tips and tails easily.
By the way does anyone have any reviews on the Jiberish x Newschoolers collab? should I just wait for the level 1 collab to come out?
