I agree with the other posts , it's a balance thing , 96 studs and 4-6 ' carbide, I would go 96/6 and adjust ski pressure & the strap to make the wife happy with the steering , the stud manu have rec charts. I just want to bring up some observations we have made regarding the dual runner skags. some people might not agree with this but... Here we go. There is the Woody's Dooly and the Stud Boy Duece on the market, we have caught the Woody's Dooly freezing up between the bars and almost 85% sure we can contribute this to a missed turn & crash. My insurance buddy crashed a lawyer, it was his bad he missed the turn. It was such a fiasco at the time that we didn't think to check the ice build up so I can't make that statement for sure ( just for the record ). BUT another family we ride with that are serious sledders had previously brought that freezing up between the bars condition to my attention originally. They are 50% UPer's and will ride extensively. Both friends have swapped out the Dooly's since. I just wanted to mention that, due to the wife having that set-up. The SB Duece is a different design and does not have that condition. Some people that I talk to just swear by them ( Dooly's ) but I have to question wether or not they pay close attention to the ever changing trail conditions they ride on through out the day. ( IMO ) As far as the W/W thing your on your own with that !!!!!
