I have a tubular disc wheel with a new Vredestein Freccia glued to it. The reason for the Freccia is that my local bikeshop only had this tube, it's cheap, and I didn't want to glue it myself. I can't really find any information about rolling resistance, but i found out that Vredestein in general isn't really fast.
Now I also have a 88mm wheel. It has a GP5000 with a latex innertube. According bicyclerollingresistance.com it's rolling resistance is 8.4 watts at 120psi. The only Vredestein on that site has a rolling resistance of 18 (!) watts. According Vredestein this is a "fast" tire, it has the same rating as the Freccia. Assuming both are equall, the Continental would almost save me 10 watts. That's a lot.
I am now in doubt what wheel to use in competition. Obviously I can remove the Freccia and glue a Corsa speed. But that would cost me about $100 and some effort. What would you use? Will a disc compensate the 10 watts "gain" from the slower tire? I am only competing on flat area's, so no climbing. Crosswinds are a toss-up.
