Familiarity: I've put it through the wringer
I cannot recommend these rims. They are a lot like Seattle, when they work they are great, it is just the amount of time dealing with rim tape alternatives, multiple flats, and LBS trips, make them un-reliable. There is clearly something wrong with the engineering of the spoke holes relative to the bead seat that caused the pressurized tire to move the tape. My advise is if you don't want to worry about flats, don't buy these rims.
