Default Warm Temp Keg Carbonation Problems

I just switched to a corny keg system and life is good. Well, sorta. My basement stays around 68-70 F year round, which is good for fermentation but bad for serving temperature. Alas, I do not have a beer fridge. So, to have the adequate amounts of CO2 at this temperature, I calculated something like 24-26 psi. Since I have a beer tap on a ball lock on my keg, I get a lot of foam. If I carbonate at 24 psi, then relieve the pressure prior to pouring, it comes out a little under-carbonate and then I have to top the keg off, using up more CO2 per keg than is necessary.

Can I resolve this problem using a picnic tap and 6-8 feet of tubing? What else can I do?

At that pressure you need more serving line (= greater pressure drop) to reduce foaming. I don't have the specs on hand, but google pressure drop per foot for the ID tubing you are using and divide your serving pressure by that amount to get your length.
I plan on living forever. So far, so good! - unknown.

When I do soda at 30 psi, I need nearly 25 feet of tubing to get a foam-free pour. If you get long tubing, like 20 feet or so, you should be foam-free at 70 degrees.
