I may be getting a pony tank at some point in the not too distant future. I dive in somewhat cold water (down to low 40s), but not typically in cold weather. I was thinking I would probably just get another of the same relatively inexpensive sealed diaphragm regulators that has worked well for me so far and use that for the pony. (If it ain't broke . . . )
On the other hand, I read sometimes that people often use a simple unbalanced piston for pony tanks. Any reason (other than saving a few bucks) to prefer a basic unbalanced piston on a pony tank?
