I have a Penn 113 4/0 Senator. Would I gain anything by adding an Accurate frame to this reel?
What about a Penn 500 Jigmaster?
JMHO, but I don't think you gain anything. 4/0 Senators and Jigmaster 500s have 30# class drags. No matter how much you increase the strength of the side plate or frame, you are still stuck with a 30# class drag and that leaves you stuck with a 30# class reel.
Like Valkyrie said, I hate graphite frames, although I have a couple GS555 and a GS525 that have given me zero frame problems so far.
If you are worried about bearing alignment in the older Penns, that can be addressed by some careful fitting of the existing Penn frame posts and the reel stand(frame).
