Are Swiss DT spoke sufficient for me, at a weight of 240 lbs for my comfort bike? ?

I have a Gary Fisher Tiburon comfort bike. I have had several problems with my spokes breaking. My local bike dealer says he will put Swiss DT spokes in for $56 dollars. I am only having this problem in my back wheel. The rim is a 32 hole Bondrager Camino.
