L3130,
Your getting allot of good responses and good counterpoints here IMO. The electric diverter is nice as MadRef noted because it's control is added on the FEL joystick. You momentarially loose the use of say the bucket curl circuit when activating the button as I understand it. The joystick movement that controls the bucket curl would be diverted to the angle cylinder on the blade until you released the solenoid/diverter button. Think I have that correct. It is a convenient setup.
Texbaylea makes a good suggestion on the separate remote. Not that big a deal to use, and the curl circuit is never defeated with that solution. Joystick controls remain unaltered. Another advantage is that if you do a rear remote and plumb it forward, you have it available at the 3PH for other uses.
Really it just gets down to cost and prefferance. I don't think the cost is that far apart. Few hundred $$ more maybe for the remote and lines up front. Mine was about $1k and others have had it done in the 750 range. Also, once you have a remote out back, additional remotes are reasonable to install. The first is the big dinero.
You can also do a remote at the loader mount area, but that is not the preferred solution for most remote applications. Works fine though for your immediate purpose. Just stacking additional remotes on there ,later, may not be desirable.
Guess we'd all eventually like to know where you land on this. Any of the options cited are good, just a matter of best for you.
Good Luck,
