I went from a 70# PD to a 101# Terrova and love it. My PD would overheat when pulling cranks and really use up my batteries. On spot lock, they both do the same. When you start drifting, it will turn on at 1/2 speed, then 1 speed and by then you've drifted about 15 ft off the spot. Then it will go to 2, 3, 4 speeds and here you go. Lol. If there was a way to have the motor first turn on at about 3 speed it would work great.
