I agree ... back in my ATV days I installed Motion Pro twist throttles on all my quads. They just seemed effortless and with some experience they aren't any more dangerous than the thumb throttle. I have moved on to side x sides and the foot controls are even better.
He11, I'm to the point now where I almost always have my 8yr old son with me and I let him take the wheel while I kick back, relax, and enjoy a cold one! We are both happy in the end.
