I'm on my 2nd shee, the first I had when I was in high school (12 years ago...) I had a twist on it but didn't care for it too much.
12yrs later.. I hated the thumb throttle on my Honda 450R so I coverted it to twist and love it. But the shee stays thumb because I don't mind it...
I guess what I'm trying to say is "to each their own". Try it, if you don't like it then put it on ebay or for sale on here and get a few $$ back.
It's all about preference.
