If you have never used one, I suggest you get a cheap one. They are very hard to get used to if you have never used one. Thump throttles are easy to used and you can just take your thumb off when you get in trouble. Sometimes you can get in trouble with a twist, so, for now, I would suggest the long throw just so you can see how it works. You would be suprised how many racers used thumb throttle. Sometimes it's because that is all they have used or they just feel more comfortable with one. I grow up on thumb, but I did try the twist. But, everytime I went into a burm I keep blimping the throttle and I would get out of control. Just a thought! :lol:
