I have tried just about every mount on the market so far with 12″ and 16″ graphs. I personally did not like my Cisco’s at all. They’re rock solid mounts and I like the ease of taking everything off, but I could not for the life of me keep the set nut on the arm to stay tight. I tried lock tite and everything on mine. Worse thing possible in rough water to have that come loose and then a 16″ graph spinning into the windshield.
Ballzout was ok but couldn’t keep the bolt that holds them base into the arm in one piece. Had a couple of those break.
I made the switch to Fin Gears new mounts. Hands down the best mounts I have used yet. Stabil also makes a decent mount, but Fin Gear gets my vote.
