I had S6F for 1,5 years.
While it was easy to get vertical, the bottomrocker made it behave less than optimally at times. Eventually I grew to like it, but it´s not one of those, that I could jump in and feel right at home. Took a lot of outfitting and effort..
After S6F I wanted an allround and found it in JK superstar. No surprises for me anymore , thank you
