I would echo that 4 more spokes is nothing weight-wise, but could result in a stronger wheel. However, a good wheel with quality components are likely going to be the bigger issue than spoke count. I've had spoke issues with 36 spoke wheels and with 32. Generally my criteria is: can I get my desired hub/rim combo in 36h? Do it. If not, 32h gets the job done. I'm also currently riding a 26" wheel with a gear hub, so smaller wheel + higher flanges = shorter spokes and a pretty sturdy wheel. Not to say I sever have issues, but I feel like I'm more likely to damage my spokes when packing/shipping/checking the bike than when riding it.
