If it fits in your pot, you can't really have too much. Now, there's a law of diminishing returns at work - by the time the water reaches the last ten feet of the tubing, it's already been warmed up by the wort a good amount and won't pull out MUCH more heat - but it'll still be better than a 25 foot chiller.

What you might think about, though, is to use some of that tubing for a prechiller, especially for the summer. Run the water through a bucket of ice before it goes through the wort.

If you have a pump just cycle the wort out of the kettle and back through the top to a tube set at such an angle to create a whirlpool. This way you don’t have to stir by hand and you get an automatic whirlpool. Jamil Zainasheff spells it out on his web page.
Not sure what you mean by bugs, but when you stir, you aren't whisking or anything, just swirling the wort to make sure that you aren't getting a cold pocket around the chiller. I have a 50' 3/8" chiller that gets my 6 gal batches down to 65 degrees in 15 minutes, and under 150 in a couple minutes.

I might be overly paranoid, but stirring cooled wort to aid in cooling and/or to whirlpool makes me nervous. Who knows what kind of nasty bugs (bacteria/wild yeast) are in the air or even fall off your arm. The reason bottle trees work is because the bottle opening faces down and bacteria and wild yeast don’t fall up. I like the whirlpool chiller method because it lets you cover your wort right after boiling and leave it covered.

I try really hard to keep the spooge out of the brews though (except cream ales).

Thanks for perhaps the most disgusting factoid I've heard in the past two years.

Exactly what I am saying…I love my wort soooo much I’ll take drastic measures to protect her. That said…the added spooge does negate all my hard work. Your welcome.

A question for you guys:

I can get 12' of 1/2" 'M' (much lighter than the tubing labeled 'L') for $15 CDN, would that be sufficient for a chiller? How difficult is it to bend 1/2 tubing by hand?

You need the soft stuff that is sold in a coil, not the individual straight "pipes". The soft stuff is just easy enough to tighten up the existing coil, but anything more than a 6" radius is asking for a kink. They sell spring sleeve anti-kink devices for each tubing size if you want to make a more drastic bend.

Ah ok, damn, guess I'll have to look harder....
