compressed air piping

New 2 stage vertical 80 gallon 175 psi installed and will be installing new piping from compressor and around garage shop.

Not sure if 1/2 inch pipe big enough or 3/4 better. Planned to get the RapidAir setup, but really not sure if I should use it or go with straight aluminum pipe or black iron.

I know (or think I know) I need to run some type of manifold first as I have limited space (less than 50 foot from compressor to paint booth / area), but not sure what setup or combination works best.

Any thoughts surely appreciated!

    sorry, meant to say I'm running a blast cabinet if it matters.

    @winter I use the 3/4 rapid air system and I love it. Easy set up and even though the fittings are higher than other methods I think it's worth every penny. 
     I would not run black iron due to them rusting. The only options I would consider is the rapid air or copper piping. And which ever one you decide I would run 3/4 lines and reduce down at your drops

    See my thread "Opening a Hydrographic Business"...we spent many posts discussing the pro's and con's of air delivery systems as well as construction using various materials...

    Rate your system for the amount of CFM you need to supply to each piece. That will give you your pipe size
