Hi everyone, I'm new here. Brief background; I am a landboarder. A couple of decades ago I was flying a stack of fexifoils with a skateboard that had 2" risers and 105mm XT Wheels.This was before it was really a thing. During lockdown (March) I decided to get back into it. Got myself an MBS board and PLK Uniq 3.5 single skin, just because it was all that was available locally, but tbh its kind of meh. Getting to the point though, I just ordered a race kite. One seller had a 4m Ozone Yakuza (very old stock), another had a 4m Ozone Quantum on clearance. I went with the Quantum being that it's the Yakuza's successor and their marketing calls it an improvement. What I'm wondering is does anyone here have experience with both models and have an opinion on whether the Quantum is actually much of an improvement? Why I ask is I'll probably grab a smaller one next for high wind days, and the guy selling the Yakuzas also has smaller ones left in stock (2.2m), or alternatively a Blurr 2.5. The place I got the Quantum only had 4m left though.

I don't know which is better.
But if you got to kiteoregon.com on Facebook and ask Eli Anderson he will have your answer. He is an OZONE guy, and has, I am sure, flown them all.
I have a 3.5m Blurr. It doesn't look like its a fast kite, but on the playa it just kept building and building speed with the apparent wind. Not sure I found that kites limits that day, but I sure found mine. Having said that, I'm not overly experienced. I had PLENTY of room and decided to keep the kite low so I didn't get yanked, and run with it. Felt like it took miles to head upwind and slow down. I'll never forget it.

imo...
you need to go on to a depower kite its way more enjoyable w/ a board

I agree with abkayak. I've been landboarding since 2006. Started on high profile FB kites like the JOJO RM and Begos. Ultimately moved to depower and never looked back. Race kites were great for speed, upwind performance and jumping but were a bit too punchy for me in the long run. I think Dean or Dan flew Yaks and maybe they will chime in but they are buggy riders.

Agree with both above, get a depower. Biggest question is where are you? If super gusty, maybe think about an arc (I'm partial to Phantom 1, but you would probably like Charger 2-3) or single surface like FS Peak or Gin. FS Speed 3 and above also handle gusts fairly well and are more high performance than single skins. Ozone Chrono, FS Soul would be in same camp. FS Sonic 2-3 are high aspect and need some skill to use, but are very fast and great jumpers. Do not take those out into gusts or you will end up with a ball of yarn. I would not recommend those (or the race variants) as a first kite. There are other kite brands worth looking at, but FlySurfer and Ozone are the 2 main ones making foils. Ask here if you find something you like, and give us your location/conditions.

BTW - my Blurrs are my favorite FB kites - as Colin states above, they are mid/high aspect, fly very forward in the wind window and once you get going they rip. But FB on landboard can be difficult to eject, depower is much safer.

I do have an old Arc 630 here from the late 90s. I'm not really using it because I haven't kitesurfed in forever, not sure where my seat harness disappeared to, and from memory it got me a bit more airbourne than I'd like to be over solid land. Guess Im a bit heavier now though. I feel like it was a pretty fine line between enough wind to keep it up and too much wind to handle it. As for ejecting from the ATB, I took the F1 bindings off mine and replaced them with some Freebord bindings. Way easier to step out of if I need too, and I wasnt planning on jumping it much anyway. Prefer to just go fast.

Also, Im in New Zealand.

Arcs (and all kites) improved in a huge way past the 630, completely different animals. Phantom in particular are very docile landboard kites.
The ejection I was talking about wasn't from the land board, but from the kite. F1 bindings are great, just keep them a bit loose if you feel like you need to bail a lot. Modern depower kites have quick release systems that let you flag out the kite immediately, and a back up full release of the kite if you need to eject everything. Fixed bridles - if you have a strop can sometimes be hard to get out of your hook, and if you're just holding on with no strop will tire out your arms pretty quickly. Depower kites also handle bigger high and low wind limits than fixed bridles, so you need fewer kites to handle every situation.
Having said all that... you're asking about Yaks, Quantums and Blurrs, I know Yaks were great kites, no experience with Quantum and Blurrs are great.
What are your conditions, where do you ride (beach, pavement, grass etc...). I know Plummet and Kamikuza are in NZ, but it's a big country, not sure if they're near you, but if so, you should definitely get in touch with them.

Thanks for the replys guys. All very helpful info.
I had already heard great things about the Blurr, so that helps make my mind up. I'll grab the 2.5 from our one good kite store here. I plan on using it on grass when the wind picks up around 20mph.
My 4m Quantum has arrived from Oz, sort of. Convinced my wife to get it for me for Christmas. Its going to be a couple of weeks til I can actually fly it.
