Over-Rev Question?

One more hat in the ring here (and a suggestion) ...
I experienced a significant over-rev due to a miss-shift (12,000 miles ago) due to several factors. My transmission had been previously rebuilt by Honda under warranty, but had actually progressively gone downhill after the rebuild. On the way to the dealership to get the transmission ultimately replaced (after fighting to get Honda to replace the transmission), I experienced an upshift miss-shift that resulted in an estimated 10,200 RPM. The transmission rejected the higher gear (several times at or near the lower gear's redline point) and ended up downshifting as I was attempting to force the transmission to give me the desired gear. My frustration created a lack of SA.
I experienced no immediate obvious ill-affects and have not seen any problems as of yet. I had the Honda dealership that replaced the transmission pull my cams and inspect my retainers and keepers while it was in the shop. I was there during the inspection the dealer gave my valve train a clean bill of health (and I personally observed no problems). Nevertheless, I've continued to inspect the retainers every 5,000 miles as a preventative measure. I have the process down to around 1.25 hours.
Suggestions:
- Never skip shift - this is not good for the transmission and leads to sloppy shifting.
- Have a trusted Honda mechanic inspect your retainers if you believe you really over-revved your motor. The full inspection (pulling cams) takes no more than 30-45 minutes more than a standard valve adjustment, and will give you piece of mind.

No arguement that if you -actually- over-rev your car you should check out the valve train. But in this case the guy didn't do it, and billman the self proclaimed "best s2k mechanic" seems more than willing to convince this guy he's gotta pay him $ to inspect the valves. When this "best mechanic", doesn't even know the actual redline of our car 
to do 10500 rpms in 2nd (where honda has told us float occurs) you would need to be doing 77.5mph.
