The Lib & GNU web sites are confusing. Which of the boards have the least rocker. In the past I had been looking at the Phoenix(not crazy about the base), Riders choice, DK, TRS &Trice.
For Lib-Tech there is really only the new C3 Jamie Lynn (which basically camber with a dip in the center) and specialty boards like the La Niņa. Otherwise mellow C2 like on the Phoenix.
More or less the same for GNU, only you have even fewer options - Danny Kass board is as camber-ish as it gets.
BTW, nothing wrong with the base on the Phoenix. Or is it that you do not like the design?
