My main board is a Carved Imperator V 139x44, I use it from flatwater to overhead waves, everything. (I'm 85kg)
Very very comfortable ride, it eats up chop like mad, very easy on the knees as it smooths out all the ripple. Planes early, I've used this board in very light wind with my 17m kite while on vacation without my LW board and it does a great job, but it also doesn't lose it's edge at speed. I've ridden other boards that just want to skip out from under you at speed, this one does not.
I've also got an Imperator V 133x40.5 that I use less frequently than the 139x44, it's great when really powered up but I mean really powered up. It has about the same amount of rocker as the 139 but over it's shorter length so it chews up power a lot more. You can change your weighting/stance to make it more efficient but I find once I've programmed myself into my 139 it takes a few passes to dial in my form for the 133.
I've ridden my Carved boards back to back with a CORE Fusion 137x41 as well, the Fusion definitely transfers more of the chop feel into your feet and legs, it just felt stiffer in that respect. I am taking a Fusion with me on holidays soon and plan to put more time in on it, I should have some more comparative feedback in a few weeks if the wind cooperates.
