Well Jack,
Here's my experience:
Started riding ATCs with thumb throttle.
Then Quads, quad sport, Banshee, YFZ 450 all thumb throttles.
Been down the Dirt bike twist throttle road just to find a titanium rod in my femur.
I've ridden Quads with twist throttles and I had way less control of em. :black:
So, basically I think you need to ride a quad with a twist, before you go change yours.
I know lots of 2 wheeler guys that swear by the twist throttle regardless what it's on.
That's just my $.03 .... I threw and extra penny in cuz you read my post. :clown:
