Before I started whirlpooling with a pump I would just sit next to the kettle and gently rock it back and forth. Not enough to slosh the wort around, but it was plenty to keep that output hose hot.

Perhaps I live in a black hole with no oxygen present?
ditto. from the minute i drop the IC in i'm whirlpooling and have never noticed an oxidized flavor. def cuts down on water usage and time, plus you wanna aerate your wort prior to pitching the yeast anyhow. i don't see a problem...

Just use an oven mit

I personally use a 5/8" chiller that I made and just gently raise and lower it while it's chilling. It drops 5.5gal from flameout to 70 deg F in 10min flat.

There's no puddle of cool wort on the bottom of the keggle. What's going on is that there is a temperature gradient that forms around the coil, dropping the temperature locally and reducing the transfer of heat from the wort to the coil. When you move the IC, you break up this gradient, which jacks up the difference in temperature between the coil and the wort, radically increasing the rate of heat transfer.
Short version: Don't raise the coil, make it (or the wort) move constantly.

Works fast and settles out a lot of break material. Here's a recent brew - note that I did use a hop bag!

Why do you have two pickups in the kettle?

If you're whirlpooling, you need a feed and return line.

Duh. I'm so used to my setup with the input on top of the kettle with a silicone hose running to the inside bottom of the kettle I didn't think of the return being so low.
Is the one pickup with the cap the out or the in?

The reason is I'm asking is I get a lot of trub in my center mounted sanke pickup with a false bottom.

The short one on the bottom is the pickup tube. The long, angled one is the whirlpool port.
