You're not very far from Clermont, so you do have some decent elevation to explore, rather than flat riding only. You didn't mention your weight, but going beyond 50mm could lead to getting tossed around on windy days, especially if you're light. Plus the aero advantage over 50mm would be minimal. Actually, don't expect to see much improvement going to a more aero wheel unless your riding in the low 20's or better. But as said above, if they make you want to ride more and give you inspiration, then go for it. They can be a good motivator to get your speed up. Once you get wheel fever it's tough to pull back. There's plenty to choose from so take your time shopping. While your at it, include Boyd wheels in your search. Good luck.
