That's a good point Rusty.I note you have two good #5 rods, 9ft and 10ft, plus numerous #5 lines. You want to upgrade to something a bit more refined but still a #5.
To be honest, I think you ought to take this opportunity to diversify to another line weight if you want to further your fishing capabilities.
I know #5 tackle has a wide range of applications but it will not do everything and handle all conditions.
Sorry if I have rocked your boat.
Contrary to the other chaps who suggested I shouldn't upgrade.. my Wife will not be happy with this development!
A 6/7 weight for larger waters and more sunk line work perhaps wouldn't go amis.
