One difference on the rollerskis might be that you are raised up 3mm on the
R3 Classic and 5mm on the R3 Skate as opposed to the old NNN-II. I know
that a couple of mm here or there might not seem like a big deal, but in
cycling it makes a big difference and since rollerskis are already so high
as opposed to skiing on snow.

I still have the NNN-II on my roller skis so I cannot comment on the
performance here, but I noticed an immediate difference on the snow.

I have no idea why it is. I thought the NNN III with the wider platform
would feel more stable but the opposite is true. The difference was
instantly apparent. I have no experience on snow as I use the Pilot
system.
Curious but true.......
