Last season we had 2 rmk 800's in our group the snow was deep one had a finger one had a challenger or a series IV can't remember, in the deep the finger doesn't work at all he was getting stuck all day and we were helping to get him out it sucked. If you have to get a finger i would get a maverick seen one on a m7 this season and it worked great but the snow wasn't as deep and fluffy as last season. The finger track works good in springtime conditions but in the fluff you will not like it. IMO
