I have a 2008 Ranger Crew with a full cab so she is kind of heavy.  It is on Prospector Pro tracks, I see they make an upgrade kit to the Pro-S series.  I know that the upgrade kit consists basically of a new drive sprocket.  My existing sproket has 25 teeth and the Pro-S has 23.  The smaller sproket is give me more torque and less speed from what I hear (makes sense to me) and more track on the ground.  Well I got this thing stuck in the snow this weekend and it took us 3+ hours to get it unstuck.  Before I spend $300 on the kit I was wondering if anyone has upgraded there track system to the Pro-S and if it really made a diffrence?
