Compressor and air tool question

To avoid the water in the tool problems I ran my line in 1 1/2 copper and after coming out of the compessor i ran the line up to ceiling and back down at the other end. At the turns I added about a 6"extension off the bottom with a water faucet valve and just open them up every once in awhile when in use to drain off any water. also added a water trap/regulator at the end.
Also if you plan on needing lot's of air, do not run your line with anything less than 1 inch line and use the larger air line hose. Also be careful on fitting selection since there are so many options. The quickest way to reduce a compressor's capability is to restrict it with line and fitting size. Also be carful with your regulator selection, they also have different cfm ratings.
I did alot of research about setting up for painting cars and such before installing my compressor and they all say the lines and fittings make or break the system, along with the overall line size.
