I, too, always use one as one never knows when you may run into a CG with high pressure. I did learn last winter that there is a higher pressure regulator available:

It brings the pressure down to 50-55 PSI, rather than the 40-45 of the regular models. Might be my imagination, but it seems noticeable in the shower.
