Wheel problems
I am about 200# and carry 35 to 40 pounds of gear. I didn't want any trouble so I had a rear wheel built by Peter White and my problems were over. I still take spare spokes and the tools to repair but I have not needed them. So my suggestion is to have a good wheel builder build a wheel for you and take the time to learn how to replace a spoke even though you might never need to do so.
