Congrats on your first wheel build! After you've built and ridden your first set of wheels you'll probably never buy pre-built wheels again. When I go out on club rides on my "modern" bike I'm one of very few people still riding a traditional 32 spoke 3x wheelset. Everyone else is riding Mavic, Easton, etc pre-built wheels with low spoke counts, but I prefer to build my own because they are easier to true or swap out a rim if I need to.
