plenty of us "mere mortals" weigh a lot more than most pros and some of us, judging by the cav is god thread, can put out more power than the best of them. I doubt many heavy pro sprinters are on uber-light wheels anyway.
On the other hand while a wheel flexing may be unpleasant how slow is it really as long as you're not fighting to control the bike? During the end of your sprint you ideally shouldn't be putting anywhere near maximum force on your pedals anyway. You'll likely get more power in a lower gear spinning faster and your bike will flex less too.
Intervals even if we pretend they won't make you .04s stronger will help you ignore the flex and will help you judge what gear to sprint in better.
Still if your dt revs are annoying you and you can afford it why not get something that will be both more pleasant to ride on and more durable.
