I actually have a set of the OJ Double Duro's 101/95a Mini Combo, size 58mm that I picked up half price. I like them. I wore them in for a bit before taking them to the park. No flat spots. They're super fast and they really roll. They make crusty transition feel smooth. They are my favourite wheels for my local bowl that really needs surfacing. They are a little gimmicky, sure. They don't feel like a soft wheel, maybe similar to X99 but they have a very unique feel to them!
That is good that you have some that do work for you, as well as a great price.
I know we all tend to be quick with a poke but slow to praise, so I was thinking someone somewhere has to like these wheels, but until your message, I don't think I can recall anyone else with good things to say about them.
When they first came out, the marketing for them was pretty good, so I could see people jumping on them, but when I saw the price, I was amazed and really wondered if anyone would find them worth it, with their RRP being so high, upwards of $120 a set here in AU from some shops, so I am guessing NZ would be similar if not more.
Maybe if I had the option and then had the interest, I would get a set too, just to see how they go, but I think I am good for most things like that now. Having "shock absorbers" built in definitely sounds good for some places I skate too, especially older concrete parks that have more transition than anything else, which is where they would probably work the best for me too.
Just looking through their catalog and there are way more options in them than I first thought, most shapes and sizes, some interesting coloured core options with regular white / natural outers too.
