As the Brits might say, this is rubbish.
Not every cyclist is a 5 foot 7 120 pound TDF athlete, and even those guys wreck wheels. Stuff happens. A 28 spoke count is low for a rear MTB wheel. Combine that with an extreme riding style, and a few broken spokes isn't unheard of.
OP, as others have said, I'd try the higher spoke count, and get thicker spokes. Since you have some of the supplies already, why not try it out and see if it makes the difference. Could be a fun project and save you some heartache in the future.
