I loved my tnks, one of the best skis I have ever rode. mix of everything I needed in a rail ski...sadly just like all the rumors you hear my edges are ripping out with only like 30 days on em. I have enough epoxy in them to hold of a small shack and currently shopping for domains or dead moneys. the skis were both constructed for the same type of riding, so they will both perform at a high level for sure.
If you are charging everyday on rails and in the park like I do I would honestly say Domains. much more durable ski, and the 0 camber and tip and tail rocker are going to give you that extra what I call "park power: that some skis wont give you.
