I have the same problem with a slightly different setup: my faucet is through a wall after 5' of 3/16" beer line. (That is, no tower on the kegerator.)

I'm 99% certain that my problem is caused by the faucet/shank warming up to ambient (70 degrees F) temperature between pours. I can minimize the "first pour foam" by doing this at each pour, if I've not poured for at least 10 minutes:
1. Open faucet for 1 second (all foam)
2. Wait 5 seconds
3. Open faucet for 1 second (less foam)
4. Wait 5 seconds
5. Pour a pint (no foam)

The "waits" in steps 2 and 4 allow the faucet/shank to cool down dramatically, so the pour in step 5 is through a "cold" faucet. I can verify, by touch, that the faucet is much colder after step 4 than it was before step 1.

Can you compare the temp of the faucet before pouring to its temp after you get "good beer"? Even with a cooled tower, you might notice a significant difference.

I plan on solving (or minimizing) the problem by cooling the shank on the kegerator side of the wall. I want to thermally couple a Peltier device to the shank (maybe with a block of aluminum threaded onto the shank, with heat sink compound), so I can keep all of the metal at the faucet/shank down near 38 degrees.
