    have the potential to get heated on this -- think Mac versus Windows or VHS versus Betamax.

    After using most of the systems out there at one time or another, we settled on ASTM F1960 (aka ProPress, mostly from Uponor.)  The combination of larger diameter fittings, the practical impossibility of a "cold joint" (uncrimped in F1807 terms) and the EP fittings' immunity to hard water made the case for us. With Milwaukee selling expander tools, startup costs are minimal and the time per fitting is very attractive.  The only gotcha for us is that the brass transition fittings do not tolerate corrosive water like the bronze Viega's and the Uponor stainless fittings are insanely priced.  Sioux Chief and Dahl are adding more and more F1960 parts every year, which helps.
