Get the 50/50 set. It’ll make you faster, it’s not much more, and matching is cool.

Just get the 36/50. Because you won’t even notice that 14mm difference, and you’ll save a few bucks.

Neither! Carbon is over rated.

Choosing a set of carbon wheels
I’m getting ready to buy a set of road bike wheels. I’ve narrowed it down to two sets I like and can afford. Help me choose!
First set is 50mm tall, front and rear
Second is 36mm front and 50 rear
Other than the profile height, they’re virtually identical, except for the following:
The 36 front rim is about 60 grams lighter than the 50. Total weight for the set is something like 1460 vs. 1520 grams. It’s also 60 bucks cheaper: $960 vs. $1020.
Hubs and spoke count are the same. Obviously, the 50/50 set will be slightly more aero. Both sets are lighter and more aero than the wheels I have now.
I’m not a time trial rider. I like stuff that is versatile and durable. I’m sure with either set I’ll see marginal gains over the alloy rims I have now, nothing huge, but to me worth the cost.
What say you?

Most modern, moderate-depth rims will handle well and predictably in the wind. Assuming that these aren't some horrid, ye olde rim profiles that'll have winds buffeting you around, I'd go with the 50/50.

I don't think I would use either the 60g or the 36 v 50 rim height as a decider here. Are they the same manufacturer? Same carbon layup etc?
Personally I wouldn't be that fussed about rim height within the 35-50 mm range for a versatile wheel set. 50 mm is probably about the height where you might start to notice some crosswind effects.

Yes, they are the same in every way except profile height. They're from Hunt, in England. Pretty good stuff. The model is Carbon Wide Aero, and it comes in two different heights, so you can get a set with 36/36, with 36/50, or with 50/50... moderate price increase with each step up. Both heights are tubeless, 27mm external width, with 20 front and 24 rear spokes.

36mm isn't really that deep. I weigh around 130lbs and have 56mm rims. Not a big deal. I'd go with 50 front because the additional aero is going to (marginally) beat the 60g saved.

I try to never ride in the rain, and have only been caught in the rain twice in 5 years of road cycling.

When wet, the rim brakes on carbon wheels scare the bejeesus out of me. Not safe, in my book. And one of the key reasons I wanted a disc brake road bike.
I do ride in the rain. Also, in the midwest, you may not think you are going to ride in the rain and then you are surprised. Having lived in southern CA, i know that doesn't happen there. If rain is coming, you know it well in advance.
An alternative is to buy carbon wheels with an alloy rim track, like HED jets. If I remember reading it right, I think HED basically said that they couldn't stand behind the safety of the carbon wheel/rim brake combination and so wouldn't sell them. Maybe somebody here knows more about that.

There's absolutely no trouble riding, say, my Mavic SLR45s or my Light Bicycle R45s in windy conditions at all (the Mavics are slightly better) up to the kinds of winds where riding doesn't make sense. Like how both have no nipple holes which is nicer when running tubeless.
So with a modern set of 50s, you won't go wrong, although Hunt strikes me as typical rebadging Chinese carbon kind of company. For another CF wheelset I'd probably go deeper still with 60/80, but if you have only one, 45-50mm is a great all around option.

I have a couple of sets of Light Bicycle 55 mm rims, and when I first got them, dealing with gusty cross winds took some getting used to. It's for sure not the same as riding classic alloy rims. But it doesn't really bother me now. I can ride a well-controlled line with those wheels and pretty strong cross winds. (You know, not 20 mph gusts, but 10-12 mph, no problem. Maybe 14-16 mph I'm needing a little extra concentration).
That's 55's, which are maybe on the edge of OK for strong cross winds. My friends who ride 70s avoid them on very windy days.

I had a set of Boyd carbon hoops back in the day. Stopping power was good enough in the dry to ride around the city and do twisty mountain descents on narrow roads. Brake pads made a lot of difference. Being black, they heated up in the sun which obviously isn't a problem in Seattle but it required more judicious braking then I was used to on some of those long twisty descents when I'd take the bike to the other side of the Cascades.

Looking at their website over here, they also offer 40/50 and 44/54 options. I would just pick the depth you prefer the looks of because you are not going to notice any real difference out on the road within this sort of range.

For rim brakes I'd get Campy zonda or fulcrum racing 3.

"As well" is not my experience (dry) (with Dura Ace 7900 brakes), but as noted above, they do work pretty well. (My Light Bicycle rim tracks are also textured- not all are, but it's a feature you can request.)

Brakes are Campagnolo Record with Campagnolo carbon rim pads. Brake performance in the dry was acceptable, but not quite as good as Campagnolo alloy pads on alloy wheels. I have Dura Ace on another alloy wheel bike and I would say that the Record / carbon setup is comparable.
I rode in 20 MPH sustained with gusts to 30. I didn't notice any issues with cross winds when compared to my Rolf 33 mm alloy wheels.
And, yes. When I compared my time to a ride on the Rolf wheels with similar wind conditions I was about 1-2 MPH faster on the straight into the wind section, and bupkis on the cross wind section.
I would say don't worry about cross winds with a 50 mm wheel vs a 35 mm wheel.

I am after the psychological boost from the "thrum" of taller carbon wheels cutting through the air, but the conventional wisdom slating the stopping power of rim brakes on carbon wheels has thus far held me back.
Maybe when Broctoon starts setting new PRs with his wheels ...
