I realize that each person is different and to each their own. I would really like an F3 but I just don't have the money. I've seen a few RS models for sale and was wondering if people like them. Are they safe on the legs (example not hot enough to burn)?Also being a T8 para my core isn't that great along with a left arm that's about 6 inches shorter are there aftermarket handlebars that pull back for better positioning. I know of the ST and RT models have the tri axis bars. Any help would be welcome. I'm still kind of new to this forum so forgive me if I sound a bit loquacious. Thanks
