Why not fit presta tubes?

Usually 8.5mm, drilled lots of rims with no problems, but i'd avoid narrow section road type rims.

I drilled mine, regretted it slightly when I went tubeless as it was quite difficult to sort out schraeder valves...

^^^^ Exactly. Future proofing. I know Presta can be a bit fiddly on cold days with gloved fingers, but if the Good Lord meant us to be circumfornicating with punctures on the trail he wouldn't have invented Stans jizzm.
