I have a pair of these wheels (unused). If you were in the UK you could have them. I have seen numerous failures of these rims as the spokes are under phenomenal tension and that tension is required to keep them true. I have seen spokes snap and the rims themselves fail as the spoke is ripped out. I would recommend evenly spaced radial spokes, even when the spoke count is low.
I have rims from Aliexpress and the quality, finish and bearings are all better. I found the finish on the Kinetix rims quite poor.
You can find wheelsets with Novatec hubs on Aliexpress - these seem to be well made without being overly expensive, but allow fitting of SRAM XO, XD cassette bodies which allow SRAM design cassettes with 9 and 10 tooth sprockets which are great for tall gears/smaller chainwheels and reduction of chain length and weight, and wider or closer gear ranges. I run a 10-36t 11 speed gearset which gives good flexibility.
