In my quest for the perfect board, I landed upon the Premier F1. After riding the NS Heritage the last 2 years, which was very close to the ultimate board for me, expectations were high.
Similar to the Heritage, the F1 has great flex and is very playful as a freestyle board. Nice pop on the tip and tail, and a very stable feel when landing either way. Both boards ride exceptionally well in powder thanks to the rocker and camber.
Where the F1 really shines is when you're not playing, when you're blasting down the hill in soft/hard pack. At low speeds both turn well, however when you start going faster I found the Heritage would wash out the end of turns rather than staying on edge.
The F1 has really proven to handle this very well. It's a little stiffer, and built a little differently, and while those changes do little to change the fun factor of this board (again, compared to the Heritage) they really improve the carving and riding that goes on in between powder turns.
The Heritage was the best board I had ever ridden (loved the Lib Tech Dark Series C2BTX but too heavy) but now that title falls to the Premier F1. If you're a freerider who enjoys going fast in all conditions, but still want to ride switch and mix in some tricks on your way down the hill, you'll enjoy this board.
