I was there in November on a 160mm travel reign, found it to be perfect, could charge down everything and still ride up to do mens DH and other stuff. Downhill bike to me would be overkill, however if i only had the one bike and it was a DH bike then it would do. I
f you want to ride stuff like the Karma trail ( first stage of the EWS from 2017) which involves a long ride/stroke push up then DH is a lot of effort. Worth it though, one of the best rides i did in Finale.
Either way you will have a blast, best place i have ridden so far, planning on going back in April.
