The weekend was the first time i've ridden anything other than mervin since i've been any good at snowboarding, so the turn around in my mind is probably a little more extreme than is perhaps warranted. I maintain that they are heavy boards compared to the nitro but I can't speak more highly of my carbon credit as an entry level board. I suppose having liked the nitro so much i felt a sense of liberation but obviously based on mervin's following they suit plenty of people and they would be more so in the mix in my mind if i were riding pow and as you said, big mt more often.
Also, you are absoloutely correct about trying before you buy. Each brand has a different feel and i will probably get demos most days i head up for the rest of the aus season. demo days are a god send!
your reviews are full of flaws. u already admit that the boards you tried are way too big for you.... so why not try something your size and then compare apple to apple?
also i agree there's not a single board in mervin's line up that i would jib/park with... their boards are best for riding and is one of the best at that. take a suv on to the track doesn't make sense. nor is taking a porsche off roading. they each have their own purposes
