I know this has been mentioned in other posts, but some plugs just simply fish better. you can grab ten tomic 602’s off the shelf and four will outfish the others. i don’t know the reasons why. maybe iron noggin or another old school commy plug guy has the reason.
it’s prolly the reason you’ll find perfectly good looking plugs at the junk store. the ones you want are the ones covered in teeth marks and show the crescent shaped wear mark from the hook on the underside of the plug. that plug is swimming properly!
