I'm pretty sure that the lack oflongevitiy on the part of my personal Synergys has been caused by me forgetting to hit the button [:@]before shooting rather than just being too flimsy to fight the fish.

They may, in fact, not be up to the challenge, but I can't say that for sure until I have one fail when I've done my part right every time.
It might be a while between me forgetting, and sometimes accidentally brushing the handle on something after I do remember.

I'm hoping to hear that the Rhino, Zebco 808, or the New Muzzy reel is the answer to the problem.
