Anyone race on Gigantex CF Clinchers?

I have some Blackwell Research 50mm clinchers that I plan on racing on this season. Nice wheels for the $, but they do have a quirk. The braking surface is not at the furthermost outer edge of the rim, it's ~5 mm's away from it. I assume it's for heat dissipation issues. So when you are using these wheels you have to move the brake shoes to their lowest position. No problem when you are at home. But last night I have a "uh oh" thought. What happens if you flat in a Road Race and have to take a wheel? The brake surfaces won't line up with my brake shoe positions. Anyone else had to deal with this? Almost all the flats I have ever gotten are on the rear wheel, so I guess I could just try to remember to not use the rear brake unless I had to, and rely on front braking. Not a great solution and possibly dangerous. I'd hate to get back to the start and return a wheel with marks all over the rim from my brakes. I'm pretty sure there isn't a good solution to this.

Nate, those rims are awesome. Raced them all last year. Tough as nails and stiff. The braking surface isn't a big deal, you'll still make pad contact on support wheels, it's not perfect but it'll get you by.

Nice looking wheels. Maybe the braking surface is in that location so as the carbon wears down from braking, it doesn't affect the strength of the edge holding the clincher bead.

Thanks Race Ex, I put on my neuvation wheels and they barely made contact, I'll try tweaking the shoes a bit so I can get more contact on them, but still contact the BR surface too. Maybe try my old bontrager selects too. As for the toughness, yes, they are tough. I spent last weekend in Ft Worth training with an old race buddy and despite his reassurance that the Sat route would be fine for my BR wheels we ended up on the Trinity Trail, sidewalks, off curbs, jeez... But the wheels just ate it up.
