Before you get rid of that 5wt. give it a go with something like a SA GPX line or even dare I say... a 6wt. line to see what you think first, if you haven't done so already. That is a good stick for certain situations like where you are chasing bigger fish in smaller, more confined streams or as a tailwater rod when you have to sometimes fight a good bit of wind.
This is good advice. I find alot of TFO models really benefit from an "upline" one line weight from the suggested wt on their rods.
