I'm going to be adding another 2 spool valve to the back of my tractor and integrating the one already there into the hydraulic system (finally!) so I will no longer be using the rear SCV to run my top and tilt OR my stump grinder (not both, just one or the other ) and having to hold the SCV lever to do anything for that matter. As such, I'll be deep into the plumbing and it'd be super easy to add a genuine power beyond circuit to the tractor. The only question is should I or not?
The only real down sides I can think of is that it takes a little real estate, and I'm not sure what I'd use it for.
