I am putting the 21/49 gearing in my 2016 M8000 Ltd 3” 162”, and also want to put in the Dalton adjustable weights. What is everyone’s experience with them and what size of base weight do you normally run? Was looking at the QA2-67’s, or the QA2-70’s(adjustable from 67g to 74.4g on the 67’s or 70g to 77.4 g on the 70’s) the sled is completely stock other than the gearing and would be running at 2500-6000 ft elevation most often.
