IC configuration

I just bought a IC chiller at a LHBS and I had a question about coil placement

I use a 7 gal turkey fryer pot to boil in and it is tall and narrow. On the chiller I bought all of the coils sit way at the bottom of the pot on a lot of the chillers I see for sale the coils are spread out in different configurations what is the pro and con of different coil config and what is the groups suggestion as to how to set up my chiller btw it is a 3/8 " 25' model

As long as the coils aren't pressed right up against each other, and you circulate the wort (whirlpool, or stir gently), it shouldn't matter much. Better to have them all close to the bottom of the pot than to have some of them exposed above the liquid level.
