Just to update Nivek's review, I demoed the 2015 Burton Custom FV (twin, hybrid) last weekend, along with the Salomon Craft and Jones Flagship. I like the Custom FV the best of the three. Not done the research but from what I understood from the reps, the specific board I demoed was a directional twin (a little stiffer in the back).
The board is a great ride. Of the boards I own, it's a little more stable than the Salomon Sabotage, more playful than the Lib Tech T Rice and maybe closest to the TRS. The Sabotage still beats the Custom FV in my opinion. Although the Custom FV may have a little more stability over the Sabotage, the Sabotage is definitely more responsive edge to edge. Still, the Custom FV is an enjoyable ride and has a lot to offer. I thought it held an edge really well and was surprised given the amount of rocker in between the feet. I'd like to see how it rides in pow--which we just haven't had in the NW this year. This board is a definite quiver killer. I could tell that it would perform well in a lot of different conditions. Very strong intermediate board, pushing advanced.
I also have a TRS, and I would agree with the comments above. I think Custom FV is superior to the TRS. The mag on the TRS gives it a sharper turning radius and for this reason the TRS may be a tad more playful, but it's kind of a clumsy playfulness in my opinion. The Custom FV is smooth--it was a real comfortable ride.
I got to say--the Custom FV that I tried had one of the coolest graphics. It was a limited edition only available to folks with Burton (so I was told). It was pale grey with the stenciled backside bare shoulders and hair of a lady. Sexy but classy.
