My hope was that this will be good for handling in crosswinds. I am about 140-145lbs, so I went with a 45mm deep rim in front (50mm in the back) - I was concerned that I might get blown around a bit with a deeper front wheel.
This morning I went out for a 60km ride, looking for crosswinds. There were a few times the wind picked up from the side, enough that I was having to lean into it, and there was no steering related excitement - certainly not worse than my 30mm box section alu rims. So far, so good.
PS Just realized, there are profiles and basic specs for the 45, 50 and 88mm deep UPower rims about halfway down this page:
