If it was me I would make them 24 spoke wheels. Skip every other hole in the rim and every third hole in the hub. I have a very early Bike Friday Pocket Rocket with 24 spoke rims/wheels and 36 spoke hubs. Got it in 93/94 and still working on the original wheels. No spoke breakage so far and I am in the 200 lb range. The advantage of 24 spokes is they are all the same size. Roger
