Is 32 spokes enough for a bombproof commuter disc wheel?

This isn't an mtb question, and I'm not an mtber. I'm just thinking of converting my Crosscheck commuter bike (pic) to front disc, using an XT M775 hub, Mavic a719 rim and some kind of straight gauge spokes. And I figure that yall know discs better than any of the other subforums. So I'm curious, will a 3x 36 spoke wheel in this spec be overkill? Alternatively, would a 3x 32 spoke wheel be beefy enough to last for a long time without breaking spokes? I am 180 lbs and ride fairly aggressively as a commuter, which is equivalent to very gentle mtbing I guess.

A lot of 95kg+ clydesdales are riding on 32 spoke wheels myself included. I use a cyclocross bike with disc brakes and my wheels were built with DTSwiss 2.0 stainless straight guage spokes laced 3x with brass nipples. I've had no problems at all with the wheels. If you're truly looking for bomb proof commuter wheels then check out the clydesdale forum members' bikes - http://www.bikeforums.net/showthread.php?t=150310

32 spokes is fine. With all my gear on, I'm over 200#, and have yet to break a spoke, even on a decade-old road racing wheelset [butted spokes, alloy nipples]. I wouldn't necessarily go with straight-gauge spokes, as I recall butted spokes actually being stronger due to <insert metallurgical concept here>.

Given the XT hub, I think a well tensioned 32 hole Salsa Delgado would be enough. I'm only 150 lbs. but I've done everything but hit a curb square on with the 32 hole Ultegra Open Pros on my Soma and that includes more than a few 8 inch drops at speed. However, doing a few of those same drops while loaded with about 40 lbs. of groceries did knock my rear wheel out of true. I think the 36 spoke Bontrager Mavericks on my touring rig could probably handle such drops while loaded with groceries. Here in the Happy Valley that's total overkill even for the most aggressive commuters.

I'm presently having a set of 700C open pros laced to 32H XT disc hubs. I fully intend to attempt a mountain bike race on them when complete. So I hope it's more than fine.
