With that high of pressure I would not use PCV. I agree that some use it and have never had problems but most of the time they do not use it above 50 lbs or so. I think that is even too high.
Yes there is many different types of PVC and some would work better than others, but I would not use it at all for that high of pressure. You would be asking for trouble...in my humble opinion.
I would use Pipe for this specification. Yes black pipe will leak down. However, you can get a seal on it but it is very hard to do. But do you leave your air compressor on all the time or only when needed. If you turn it off when not in use, then pipe would be the way to go.
