Dynastar vs. K2 vs. Volkl

[CMCM]

I've kind of narrowed down some skis I'm interested in....
Again my stats are 5'7", 145#, solid intermediate, probably level 6. I stick to the groomers, I don't ski that fast, I'm looking for something to help improve turns so I CAN go a bit faster, good edging capability.

These have sounded like possibilities:

K2 Burnin Luv, or perhaps One Luv, perhaps Tru Luv, in that order

Dynastar Exclusive Active, possibly the Carve
D. Ex. Legend (purple one)....might not be shaped enough?

Volkl Attiva Aire, possibly Luna

Nordica: Drive


Any input on these?

I'm currrent skiing 06 Nordica Olympia Serenity, 150, was rated as an intermediate.

I'm wondering if I should bump up to 154 or so on whatever I get.
Would extra length be better in turning?

I stand by my K2 One Luvs and I like to ski the groomers and a few SOFT bumps! I ski on 167s.

Wait for other's reviews. I don't know enough about the other skis to give you feedback.
