Thank you guys for the feedback... all you guys seem to be on the side of the fence I want to get to (the low foam/greener side), so please don't take the following as any sort of argument or disrespect, because I appreciate any knowledge being shared with me... I just want to understand... and also I'm sorry for the length of this post...
I'm definitely going to get myself some more beer line, which previously I was against, because I think MAYBE I now understand. Please tell me if my thought process makes sense....
... In attempting to "balance" my system, since I read this is basically the first thing I should do to ever expect good beer, all tables and charts mentioning length, let's use this one for example:
urge me to go shorter as the temperature drops. I've been using the temperature inside my kegerator, which was incorrect, as I should have been using the one inside my beer tower? though this table does not go to the 58 degrees i am now at in my tower, I can see that if the pattern continues, 60 to 70 degrees would indeed require about 10' of line. So is this the reason 10' is suggested, because it's balancing the system for us "hot tower" guys?
If that logic was sound, then would the system then not be out of balance, after the first half pint because then the beer would be at the 33 degrees of the kegerator. Again, I still don't understand the tables that well to know the impact, but it would seem to me that the beer would now be over carbonated at this point? I'm making this assumption off Beer absorbing CO2 better when it's cold, and now the pressure is higher to get the beer through all that line.
Either way I still am going to get the longer beer line, but IF I am able to wrap my head around what's going on, this baby might one day be able to feed himself....
That being said, I still want to cool my tower. I understand the idea of all the warm contact winning over the cold, however that was my reasoning for the insulation and the filling of the void at the top. If there was no room for warm air, and no contact with warm surfaces, other than the faucet (which I would hope wouldn't have too big an impact, because I can't change that variable), the copper would conduct the cold up, and the insulation would protect it from any warmth.... with the only limiting factor on the cooling being copper's physical ability to conduct temperature.
For now I want to avoid a fan because honestly getting that wired, built, etc is just entering a whole new area of ignorance for me, even though I agree with you guys 100% that this is a sure way to achieve the result I desire. I thank you for those tips, and will keep them as a future option.
Brad however was able to get the result I want, by doing what I feel is pretty much the same thing I did, I just don't understand how we got different results (This is assuming his "1C" means one degree). His spray foam filled the tower too preventing any air circulation, and he also filled the top void of the tower.
Thank you guys again, and I can't wait to see how the beer line helps.
