I've had folks telling me for decades to be careful of spoke/spokehead interference with high crossings. I have done 4X 36 hole on some quite large flanged hubs with real interference. It has never been an issue. If I build the wheel properly, spoke breakage doesn't happen any differently or more often.

My theory on this is that the spokes take the appropriate bend as you build the wheel and the first ride, just like the J bend at the head settles to a new bend at the spoke hole n the flange. Once these bends happen, they don't change and are never an issue later.

I won't argue the theory very hard. But my current 4X Campy Tipo front hub spokes on my winter/rain/commuter go ~6 years on three different rims and I might break 2 spokes, probably at the threads. And there is a little interference at the heads.

87mm hub diameter? My Tipos are 75mm. That's 1/2" diff, 1/4" on the radius. I suspect you could lace these up 4X without issue as long as you could sleep at night knowing of the interference. 3X probably won't even touch. If it were me, I won't 2X a second thought. I'd try a few spokes in, enough to see what 4X looked like. But I am guessing I would be more willing to hear of 5 years of "you have too many crosses; you are going to pop heads" than you are. Go 3X.

Edit: Short memory. Totally forgot I said almost this two weeks ago!
