1. Settle down.
2. 200 pounds (Clydes) 150 pounds (Athenas) are the minimum requirements. It's from a long standing competitive classification which started with triathlons (IIRC) and has been adopted by many sports that have been typically dominated by smaller, lighter athletes.
3. Real Clydesdale? It's a broad category, dude. Not everyone here needs a 3.4 pound pair of rims like the B-43. As a wheelbuilder, I'll go as far as saying that no one needs those rims.
4. Some of us 'fake' Clydes are interested in saving weight on our rigs, whether it's by using a strong, lighter weight, mid-profile handbuilt wheel or choosing the lightest, strongest components we can get. I, for one, am not interested in riding a hilly 400k on a rolling boat anchor.

So you've got your contextual reference: I'm 6'6" and 250 pounds.
My 4 wheelsets are as follows:
- 1991 Wolber T410 Alpine 32h, laced 3 cross with DT Champion 2.0 to a 1991 105sc front and a 2008 IRO high flange fix/fix rear.
- Alex DA16 32h laced 3 cross with DT Champion 2.0 to Deore hubs
- 1987 Araya 26 x 1.5 single wall 36h laced 3 cross with stock stainless on no-name hubs
- DT Swiss RR1.1 32h laced 3 cross with DT Champion 2.0 to a SON28, coupled with an Open Pro/Ultegra 32h machine built 3 cross with 14/15db spokes, hand tensioned/stressed/trued after 100 miles.

I've never popped a spoke. I've never pringled a rim. My most recent failure was actually the bead starting to bow out because I've worn the braking surface down too thin, and the wheel needs rebuilt. I'm using the same spokes and hub for the build.
