Best wheel depth for flats/rolling terrain?
I have a canyon aeroad that i use on the flats to rolling terrain, no mountains but maybe some 500 ft climbs thrown in there.I like to go for personal best times on these rides. Im 5'8 138 lbs I have 62 mm on there now and was thinking getting a set of 80mm. will it be worthwhile or should just stick with the 60's?

If you ride fast enough there will be a small (emphasis SMALL) aero benefit with the deeper rim. However, it will increase crosswind problems.
So, if you have $$$$$ overheating the outside of your thigh, go ahead. But don't expect miracles, especially if you don't ride like a Cat 1 or 2 time trialer.
OTOH - if you need to replace your wheels anyway, no reason, other than crosswinds not to go with the 80s.

Anything gained from a 'personal best' standpoint, is (IMO) completely artificial if achieved from a technology swap. ie. what's the point. Go for increase in average watts or something instead and invest in a power meter.

I agree with FBinNY: go for it, unless crosswinds bother you, but I doubt you'd notice any difference in speed.

My .02 is an 80mm on the front can be a handful in any crosswind situation plus they are quite heavy. Maybe buy just a rear 80mm and use your 62mm on the front and see how you like it first. I would think you may get more aero bang for the buck by looking at a skin suit and a more aero helmet if you have not already done that.

So for the record..... at 188lbs you do recommend amputation?

138 pounds and 80mm wheels? Seems like the crosswinds will be a significant factor.
I'd save the $$$ and spend $ on an aero helmet. If the wind tunnel tests are to be believed, the aero helmets are a huge bang-for-the-buck. Oh, and tires with low rolling resistance. And remember to shave. ;-)

I'm your same ht/wt on 50/58's. These are fine for my everyday rides but I don't think I would go for 80 on the front.

62mm to 80mm is that really a big deal? Honestly, I have no idea. I can't imagine this is going to make any significant kind of difference for someone who is not a professional. Plus the PITA part of having to possibly adjust the brakes for each wheelset, unless you get the exact same brand, same width, same brake track, I'd get tired of having to readjust my brakes for each set. And if they are discs, ugh...I think I'd rather have a root canal.

Heck, I can feel the effect of crosswinds more after switching from 700x23 to 700x25 tires on skinny, low profile 1980s vintage Araya CTL-370 rims. Going for a ride this afternoon to enjoy the effects of today's 20 mph north wind on a couple of climbing segments that usually thwart me.
But the westbound route to get there and eastbound route back home will be interesting with that crosswind. That's assuming it doesn't start swirling around randomly, which it's done several times the past few weeks.
Can't imagine riding in these conditions with deep/high profile rims.

This has to be the most anti-consumer thread ever on BF. Normally it's "buy a new set of wheels if you can get the hubs in red."

To some it's all about the depth.
you're my height and only 138....don't go deep. Deep has been pretty played out. Most all riders and racers that ride them often are going shallow.

GCN did a video on how deep section wheels help (or hurt) climbing. https://youtu.be/lC4OoBp_teg
