Share 'WTB Cross Boss with Stan's Iron Cross'

hi, going tubeless for gravel grinder/cross races. Have a pair of Stan's Iron Cross on the way. Would like a 35 tire but there aren't a lot of options. WTB now has the Cross Boss, and they look pretty nice, but i feel like a while back i heard it was super brutal trying to mount them on Stan's Iron Cross hoops.  Can anyone verify this? Would love to hear who's run this combo. Thanks!
