I plan to build a freezer conversion and remote dispense two different beers to a tower from the next room approx 5 feet away, which means I'll probably need about 10 feet of beer line. My current questions are:

1) What will work better, PVC or flexable metal duct tubing (collar to tower)?
2) Do I need to insulate the pipe, and if so, what should I use?
3) What diameter beer line should I use for 10 feet of beer line?
4) How do I hook up the power to the blower?
5) Other then looks, are there any differences between 4" and 3" towers?

I could also use some advise on a good two tap tower and drip tray for my bar... Thanks
