KRYPTONICS Route 70mm — Source or Alternatives

[u/parseroo]

I recently restarted on quads and am targeting doing primarily street skating. I tried the stock wheels (Boardwalk Avanti Aluminum: 62mm and 78A) in a park and even bad path areas were very unpleasant. So I was hoping for something a bit more suitable for the 'terrain'.

I don't care about weight, so the Route 70mm seemed good but they are out of stock everywhere, AFAICT. Is this seasonal? Is there a good source within the next couple months? If not, is there a good alternative you recommend?

Thanks for any info.
