I'm a advanced expert freerider- pow and steeps, chutes, backcountry. I live and ride in Utah. I love ripping lines in the steeps and pow.
I've had 3 NS Premieres... gotta say that the rocker makes the F1-R 172 board more forgiving and easier to ride. But that isn't why i liked these boards in the past. they were full on ready to charge, now they are alittle washy. when you really want the nose or tail to hold and give- it flexes and poops out a little bit.
bottom line i don't think i'll get the premier again, and would probably go for the titan- i just wish it came in a 172!
i still am a never summer supporter though.
