No Chill works well.
Once finished your brewing, let it cool a little then just put cling wrap over the top, I also wrap over the sight tube and the tap.
Leave it for one or 2 days depending on the temptature.
Then tip into fermenter airiate and pitch yeast.
I have brewed more than 50 batches with this method in birko urn.
Nice and stress free.
When I first started I was trying to cool in an ice bath etc, it takes for ever and was stressing me out.
Probably not easy to do unless you have copper coil chiller or a counter flow chiller.
Insulate your Urn for thr mash and the boil, take insulation off at flame out to let it cool.
Another tip that it took me a while to work out, no need to do it 1st time but perhaps for later.
If you recirculate the wort through the grain your beer will be a lot more clear.
To do this I use stainless mesh bags and pour the wort through the grain in them after mash out (dont do it past 78 degrees).
See pic of a mate helping.
One brew in a birko and one brew in a keggle with element, both with stainless mesh bags.
Have a choice brew.

Skyhook - Yep, I've thought of this. May not be doing it this time, but will definately do it for future brews.
Mill - Same again, not this time but will look at it later. My LHBS can crush the grains for me.
Chil/no Chill - This will depend on how I go for time. I will probably have to do this on Friday night after the kids are in bed, so if it's getting too late I'll probably cover it up and let it cool naturally on the garage floor and pitch the yeast the next day. If I'm doing ok for time I'll cool in an ice bath and pitch that night.
