In my plane, it can take 10 to 12 seconds for fuel to feed from one of our
tip tanks. If I ran a main tank dry, the prop stopped, and I switched to
that tip, I suspect that would be the longest 10 seconds of my life. I'd
prefer not to take that chance, thank you.

I've only flown a couple of models with tip tanks (Cherokee Six and
aftermarket tips on a Bonanza). In both of those, takeoffs and landings
are done on the main tanks. I'm guessing that's standard for all tips.
Wouldn't it make more sense to drain the tips, *then* drain the mains?
