It's hard to compare wheelsets because the build quality is such an important factor.

There used to be a joke in the auto raceing crowd that Colin Chapman designed the Lotus 23 chassis by removing one tube at a time until it broke. Then he added one back. My advice is to build the Open Pros. If they break, you can move up to Fusions for your next build. Either way, you'll know for sure if they're strong enough.
