Not sure what you mean by best ski? Stock Yam ski works very well with Bergstrom triple points, shims & ski savers for trail riding no darting & carves well also good in loose stuff too. If you want a dual carbide ski for some reason Yamaha now sells a dual carbide ski new this year as an accessory that bolts on to their sleds. I don't like dual carbide skis from Doo very bad performance in loose stuff in my past experience but if that is what you want it would be best to contact your Yam dealer for the new Yam dual carbide ski than mess around with mod pilot ski kits. Dual carbide ski made by Yam for Yam sleds.
