More than anything a soft wheel needs a harder core to keep the bearings in position, so having anything like 90 duro would definitely benefit from a more normal core.
The colour, or more specifically the see through nature makes them way more interesting to the people who like "shiny things" of which I would see many every day in the usual shop situation, when I was there before covid. Nothing against those people - it is just one of those things, but having a product like this will usually sell more units to people who are more interested in having a cool looking cruiser wheel, than if they were just a white or natural urethane colour.
Although the cruiser wheel market might have a lot of good wheels, Spitfire only had the regular wheels in look and shape, with their 101, 99, 97 and even in the 80 HD which were a little limited in what you could do with them, but still skated well in many situations.
Something more in the 90 duro range is a lot more versatile, even though some people might not be that keen, but most 90 duro wheels I have tried can still slide if you push them hard enough, but more than anything will not usually slip out, no matter how slippery the ramp is, as well as being good to get over whatever ground from A to B.
I am curious to hear and see more, but as I have seen already, some people are keen, others maybe more reserved, but they are something new, so given the chance, I would be interested to have a roll on some and see what they have come up with this time.
Just wait and see, I guess.
Everything takes longer to get out here to Australia, but at least by then most people have posted their takes on the product from USA which I like to see and read and I don't mind the wait really.
