Professionally built wheels can be amazingly durable, even for us Clydes. Proper tension is key, as is proper pre-stressing. I've had two sets of wheels built for me (others came with the bike or were bought as a set). One needed re-truing after 100 miles, and started popping spokes by about 2000 miles. The other, properly made by a professional wheelbuilder, have over 2000 miles on them, have NEVER been trued, and no broken spokes, either. If they do it RIGHT, it lasts a lot longer!
