The only spoke failures I have experienced have been due to corrosion or impact... have always over built my own wheels and joke that a 300 pound guy could ride on most of them.
I build a lot of custom wheels for tourers, commuters, mtbr's, and for tandem bicycles and for a person who was 188 would not have to build anything except a good quality wheel unless they were going to get subjected to some really extreme use.
Off the peg wheels can be bought for less than the sum of their parts so it makes good sense to buy these and have a professional tune them up before you ride them.
