HGFish,
I am kind of partial to Evoke as I have ridden one, however I am wondering what a fore more dollars will get you the the Mana and Sunova Surf.
Totally agree about having a ride on both the Mana and Surf, just not sure how to do this as none of the shops have any more demo days as it's getting closer to winter
In reguards to second hand I was thinking this however most of the boards are not that much cheaper than new so I think I will go new for the warranty side of things
For a few more dollars you get better marketing, the brand name, team riders endorsements and most "name' manufactures will argue better quality. Evoke had issues early on (deck pads lifting mainly) but didn't walk away from anyone that bought one. They seemed to have it sorted with the later versions and if you'd watched videos, there's one on here of an Evoke being ridden as well as anything else. BTW I have no affiliation with Evoke or any other brand and have owned most of the brand names at one stage.
Warranty doesn't cover dings or snaps - other issues show up sooner than later and because there's such a high turn over of boards most on here are sold chasing that 'perfect board' and not sinister reasons.
You can't go wrong with any of the boards you've listed and there are a few more that would suit too. Don't over think it, the off-shores have already arrived
