Thanks guys for your input.
Installed a paper-roll clamp back last summer, it is coming up almost a year being in service, and except for a very small leak at a pressure test port, no problems.

Operator loves it, especially the stop feature.
The fact you can use a 4-function valve without having to hang
electric valves for the 5th function is a plus. Makes the install easier and more cost effective for the customer and no pesky switches attached to control levers.
