Just some in put.
I was recently at the wind tunnel testing some wheels (Front 35, 60, 80, 88 and Rear Disk).
On the 23 wide wheel in (35, 60 and 88) the 20 SS was faster than the 23 GP4000 II.
On the 23 wide wheel in (35, 60 and 88 deep) the 23 tire (GP4000 II) was faster than the 25 tire at all Yaw angles out to 17.5
On the 25 wide wheel in (35, 60 and 88) the 23 tire was faster than the 25 tire at all Yaw angles out to 17.5
I also tested a 23 wide 80 deep Reynolds with the same tires and with the same results.
I tested the Bont aero tires on many of the wheels and they were significantly slower.

About 25 grams 23vs 25
About 37 for the SS vs 23
On the 60 wheel what was the brake track width of it? Flo is 24.4mm
When the Crr & Aero are combined (e.g. TomA's blog), lower Crr can match/overcome the worst aerodynamic performances, depending on how the lines cross. Then on long rides/races or on bad roads, the larger tire can be more comfortable.
