17 gpm pump can get away with a 7 gpm reservoir because you are close to 8 gal which would be the minimum size id go with. Glad to see its working out!
Nice! I took the beam and cylinder off my 22ton horizontal/ vertical solitter and miunted it on the forks of my Kubota. I use the remotes, and while it works, it's slow. This mighy be a solution.
