I'd hate to punch out at 750 knots. But then, I'd hate to punch out at all. GLOC nabs the best of us. Looking over your shoulder at 9 g's is never good for your health. I can't say I miss that part of flying the Viper. And in the last year since I ended 15 years of continuous flying I've grown a full inch. Scary. I turn 40 this year and measure 6'7" for the first time in my life. I'm pretty sure I'm done with puberty. I guess my spinal cord is finally starting to recover.
