I just re read my post.

To clear a few things up:

I have 2000 miles per wheel on the same bike or 4000 total. I have a stable of bikes and another 10k of miles on different wheel sets since fitting power meters to my bike stable. But when I chose to look at the difference objectively I had to use the bike that I switch wheels with. That being said I notice the same thing on my other bikes but the wheels stay put.

There is a watt difference of 12 watts advantage at a given speed. So less power to go the same speed or the same power to go faster.

My heart rate is directly related to effort or cadence. If it's a low watt effort my heart rate is cadence related. If it's a higher watt effort it's power related. I had no difference in heart rate between the two wheel sets on the same bike.

That being said I'm sure if I used the deeper wheels in Texas hill country I would prefer the shallower wheels. But 90% of my riding is done in flat Houston or the surrounding area that's flat and windy.

I think my riding location, fitness, size and speed greatly favor deep wheels.
