Personally I would go with the type 'L' 1" copper, run at least 25' diagonally or vertical before putting any fitting in except for a copper connector of the two lengths of pipe. At the bottom of this install a water drain. If you can't do this because of space restrictions then you can use a roll of soft copper (1 or 1 1/2" ) of approximately 40 ' in length. You can put a small fan on the end to cool the inside of the coil but allow room for air circulation, this will act as a mini dryer. The first 25 feet of the piping is the most critical, as warmth holds the most moisture, and this part of your system obtains its heat from the compressing of the air. The cooling air will lose its moisture as it travels up the pipe and will condense on the inside of the copper and run down the walls to the water trap below. Keep the regulators, oilers, etc to the ends of the branch lines as suggested by others. Your large supply lines will act as storage for extra air, cooled dried air, that is. If you can find an old central air conditioner coil this is perfect for use as a dryer and it has a good size fan already.

Good luck on your endeavors. AL
