I’ve learned a few things about KitchenAid mixers.
This spiral design is a superior dough hook. It solved my problem of dough climbing the hook.

The dough hook should be used only at speed 2.
I have to remember to use this thing. When I make a double batch of bread (1 kg. flour, 690 g water) it throws a little flour out of the bowl.

I ordered a six-quart mixer because they were cheap and my five-quart was in the shop so long with no response to my email or calls that I thought we were never going to get it back. I liked the 600 a lot, the more powerful motor seemed more suited for kneading stiff dough, but it didn’t work for small amounts, for example, the whisk just stirred three eggsaround iin the bottom of the bowl without breaking the yolks. Great choice for a big household.

I’m thinking of getting one of these.
