Halos will have a softer feel and butter a lot easier. Halos handle jumps fine but are definitely softer. I would recommend if you spend more time on rails the halos, but if you are hitting big jumps often the alphas will definitely be the ticket. Bindings I would suggest the rossignol FKS or the look pivots. Both super strong and sweet bullet proof and safer turntable design.
