I put on the power handle for my Abu C3 6500 and it has made a day of casting big baits for Musky much easier. The grip on the handle is larger than the stock handles. I personally feel everyone with a C3 6500 should have this handle attached!
The Abu Garcia Powerhandle was a nice addition to my Abu C3 6501 reel. I use this setup for musky and big pike so wanted a little more cranking power and better ergos. The paddle on the Powerhandle is bigger than standard so a little easier to grip. Great add-on to make a great reel even better.
