I sold the Bio 500T on the site starts with E.
Me and the stick didnt connect somehow, the SW and balance to me were under par compared to the 300T and 400T.
I know you guys said it swung light but I didnt feel that, it felt heavy and swung like a Juice Pro to me.
I may buy a 2nd Bio 300T as it is by far the best stick I've tried all year and I've tried probably 12-15.
