Hi C Johnson,
I'm a dealer for both the Litewave DV8 and Axis New Wave and know these 2 boards quite well.
Hopefully this will help.
Once up and moving well, you won't notice the weight of the DV8 and in some cases it actually helps. I can ride the DV8 with a 14m if it's solid wind and for sure down to ripping 6m and even 4m winds. I can do the same with the Axis New Wave, but the lightness will be felt if really overpowered. The ride is faster than people think. I've had guys say it feels slow, but when comparing next to another board, it's just as fast. It's kind of like a Cadillac. Smooth and solid. You can beat the crap out of this board and it will take it.
Axis New Wave advantages:
You can still ride this board in light, medium and strong winds with the right kite. If you are doing strapless jumps, it will be much easier on the New Wave due to the weight. The New Wave has a snub nose, so it rides a little longer. The New Wave feels snappier if pushed hard. I do a lot of strapless tacks transitions and the New Wave is easier to push/shove the board around while tacking.
Full recessed deck board advantages:
I've found that this style of board has a lot larger wind range. It has to do with the recessed deck and being closer to the water. Thicker and lighter boards will either be better for light and medium winds or medium and strong winds. Or differentiated on wave size, on shore, etc. So many variables.
Have you been riding surf boards much? Is this your first tone? Strapless? Looking to do strapless airs?
If you have a good dealer, that's great. If not, contact me and I'd be glad to help. I'm currently out of stock on both boards, but can order if needed.
Take care and good luck.
