Less muffled" is the best review I've heard for a cafe's background noise! Maybe we've all been paying for fancy earmuffs this whole time.

Actually, the new PEX-A stuff with the bigger inside diameter handles long runs way better than the old stuff. If they oversize the main lines a bit and use a good manifold system, the pressure drop isn't that bad. Some inspectors are just stuck on copper for commercial jobs.
