hey i am building a kegerator and have a question about a couple of draft towers that i am looking at. both are micromatic 2 faucet towers. both are stainless steel. it looks like the only difference to me being that one has beer hoses coming out of the bottom. the other has what they call bent tube housing. it looks like it has steel tubes coming out of the bottom of the tower to connect hoses to. what would an advantage of this be.
