Keep in mind, the Solitude is a way different rocker than the NS, I know they tried to bring them closer with the new profile, but think flat with early rise more thatn actual camber between the feet.
I love the Flow though, at least the NEW Solitude, the older one was a bit washy with its full rocker.
The NS Premier is a great upper mtn ripper! Very stable, very damp, easy to go fast on. Quality, as has been mentioned, is off the chart!
I ride a Jones Flagship for those days, and I like it a lot, but the NS would have been the choice if the shop had one in the size I was after. Now, though, I won't give up my Jones for anything!
