both would work it just depends, I have the one life and love them they are super poppy with a pretty stiff flex. Also they have a very extreme rocker with the three stage tech that lets them float very well in the pow, the dims perfect in my opinion and riding switch is relatively easy. The new life is 123 in waist with a symmetrical build so its meant to be center mounted. A pretty fat symmetrical pow ski, with a gradual rocker giving it amazing pow performance. Imo i would go with the one life. Has a little more versatility.
