I may be the only one using rear remotes to control a grapple but I must say that I am perfectly happy with that arrangement. If you have rear remotes or have some other excuse to get a set it makes a lot of sense to try them as a means of grapple control before investing in a diverter valve or solonoid. The cost of installing a set of rear remotes is less than the cost of adding a diverter and you get multiple functions out of it. It also requires zero skill to connect a grapple via rear remotes. Just measure for the right amount of hydraulic line and get the appropriate fittings attached. Then you just need a fist full of zip ties to secure the lines as you route them to the FEL.
I think some people are unhappy with the idea of taking your hand off the FEL controller to reach back for the rear remote control lever (usually on the right fender). I gotta say that after about a day or so of use it is no more difficult than shifting 4 on the floor. I used to look but it is totally automatic now. I cannot imagine there is even a half second lost in moving my hand. You can control the grapple just as finely as with a diverter too. I chickened out proving that yesterday when I was taking a movie of my grapple use and tried to shut the camera off by touching the shutter button with the grapple tooth....I gave up because I couldn't judge the distance closely enough, not because I couldn't control the grapple finely.
