I am a Clyde rider and will say I use strong wheels. 32 spoke Deep V rims because I have thrashed too many hand built wheels in lower profile rims like Mavic Open Pro. I get about 2,000 miles out of low profile rims. The 30 mm deep v rims give me great mileage and are very durable. I can't afford to have wheels built every 2000 mile looking to go light.
FTR, I would do a lot of climbing preparing for big rides and timed events consisting of 100 miles and 12,000 ft of gain.
The thing to me is that I have had a ton of friends tell me that I should go with a lighter faster low spoke count aerodynamic set of wheels. But yet, when I ride, they still suck my wheel even after they swear that they get a 2 mph increase of speed out of the wheel.
I think more the placebo effect. The strong fast guys are going to be fast and strong no matter what. I will say too, that if I train, my wheels feel much lighter when I am in shape. I never noticed any kind of drag with my wheels. I have even been climbing in the mountains, catching guys then having them preach to me that I need lighter wheels. WTH, I just caught and passed you on a 20 mile mountain climb of 5,000 ft.

One guy was telling me such nonsense when his front wheel fell apart ha ha ha! (Mavic Ksyrium). I found it funny he was telling me to ditch my Ultegra hubs too saying they were to heavy. WTH! I think these guys have more money than brains ha ha ha! Mine didn't fall apart on the ride.
Then I have a really super duper climbing friend that was posting on a local forum. Super fast guy, super climber. Guy was climbing 7,000 ft on every ride, and fast. He had a Specialized bike, not sure of model but a nice one. He invested $2000 into some higher end light climbing wheels. Really cool looking. I ran into him on the mountain one day and asked about his wheels that he had posted on the forum. He said he wasted his money. Said they felt really cool on his first ride but that his times on Strava were not any faster than the stock wheels that came on his bike. You would think a fast guy would notice a benefit vs us average Joe types. But he said he liked them because they looked cool but he was bummed that it didn't make any difference at all.
This is the guy right here. Got plenty of cyclists friends and forum posters on my blog so I can't make this stuff up. Got a few pics of him on my blog with the stories. This is at the start of one of his 7000 ft training rides.
This guy is going to kick butt no matter what wheels he rides as long as they are decent wheels. Fulcrum, Mavic, down the list.
