Here is what you need. About the price and the power of a good hi-start, but works like a winch. BTW if you are using a Dynaflite HD HS, I don't consider that a good hi-start. No disrespect intended.
If you don't need the super power of a ford long shaft winch or you want to avoid all the walking of pulling your hi-start out to 800 feet, take a look at the Onewinch. I have one. Works like a winch in the space of a winch but about the power of a hi-start. No battery, very light and easy to use. And a LOT less walking than a hi-start.
