Best option for CNC hangars!

Got these after I had some speed wobbles going 30+ on my TKPs, what a difference! Feel much more confident at speed, and with the right bushing setup carves just as well (I rock 88/83a riptide WFBs/95a pivot cups). Been using them about 8mos and they've held up great. Can't beat that price for CNC hangars.
