P.B. I feel you would be in good shape with a 36 spoke cross 3 wheel built with db 14/15 spokes but you will be stronger, (even though I don't see the need) with the 40 spoke wheel, that's about as close to bomb proof as you can get. Although, a poorly built 40 spoke wheel is no better than a poorly built 36 spoke wheel. You need to find a quality wheel builder to do the work for ya.
