Seeing how you have a hydro already. I would invest in a bigger pump, engine and maybe a dump valve for return stroke. You can be into the 26gpm range for less then $1000. Especially if your using a Chineese engine from harbor freight.
If you didn’t have either, I would be looking at a kinetic fir my first and only. Anything that the kinetic couldn’t do, I would just noodle it till it could. And then get one with the electric motor, so it’s quiet. The older I get the less I enjoy noisy environments, regardless of hearing protection.
