This is a true statement, for sure.
As for the wheels, are you heavy? If you're too heavy for your wheels, then no, you shouldn't ride them. Not because you might break them, but because it'll screw up your race having broken spokes or untrue wheels.
All other factors being equal, I don't worry about riding bladed spokes. My race tubular wheelset has bladed spokes with a 20/24 front/rear setup. I'm 150 pounds and I haven't broken a spoke yet. I also have 32hole wheels with butted spokes that are absolutely bomb proof at my weight.
