Mixing deep section rims

Hello,

I was wondering about mixing deep rims for some specific racing events, like crits, even with crosswinds and a lot of sprinting. Some crits around here are in very short circuit, but the master-amateur championship is a 25km circuit on road.

I mean having a higher rim on the rear wheel. For example, I've got a pair of carbon reynolds with 32mm depth. What about getting another reynolds rear with 46mm or even 66mm?

(Let's not discuss about brands, ok, reynolds is an example)

Is there any (real) gain? Or maybe I would even feel it?

Sometimes we see in competitions like TDF some guys doing that. When it's a good idea to do it? When it's short, or long, or few crosswinds, forget about it when climbing... what's your opinion and experience?

Thanks.
