I would agree...The spokes are important to keep an eye on. Make sure your wheels spin true and then check them periodically.
I run a lot of trails when I ride and the last rear wheel I had on, although it spun true, still had a problem with breaking spokes and they were the stainless ones. I soon started carrying extra spokes I got off a junked wheel then. I cut the nubs off and pre-bent them so if I fixed them on the road, without taking the wheel off, I could replace them with the help of some vice grips.
