Ok Yep understand it now, smaller the number the tighter the turning and more nimble it is correct?
Smaller radius - tighter turns, less stable at higher speed.
Bigger radius - bigger turns, super stable at high speed.
Keep in mind that that radius is true for non-drifting turns in hardpack or so.
You can turn any board in tighter radius with some drifting(i dont know exact term, hope you understand what i mean) and with losing some speed, and moment of force.
In powder you can turn tighter that listed and it'd be fun.
So don't avoid bigger radius. For example boardercross decks have 14m with 163 cm length.
I have checked the furbergs out, not a fan personally.
The radius doesnt matter in pow but you do spend a fair amount of time bombing groomers to get to the pow so its handy to have a board that handles well on hardpack aswell.
That's why i got my donek. You can check the quiver on a last page in "12-13 setup" thread =)
