Assuming you want to do primarily groomers, I wouldn't go with a pure rocker board.
The Burton Custom Flying V doesn't have a good reputation for edge hold on hard pack.
So from your list, I would take the TRS.
If you want to look for more boards, here are a ton of reviews:
Snowboard Reviews | The Good Ride
Make sure to look at the 'In Depth Reviews' and check out the review criteria at:
About The Good Ride Reviews | The Good Ride
In particular, turn initiation should be 'easy' and edge hold 'great' to 'excellent'.
My G.A.S is out of control im about a day away from pulling the trigger on a TRS, SB or a NS Cobra. Need to figure out which I will most likely feel more comfortable going high speeds with.
BTW That is an awesome website that should keep me busy for a while.
