Well I can proudly say I am down to 9 (of mine), I have my fathers old rod and 2 of mine from my youth in the garage. They never get fished so they dont count.
I sold off a 3wt and 2 5wts. I had 4 3wts now I am down to 3 of those and no 5wts. I just decided I have a 9' 4wt so no point in having a 9'3wt to use once a year. Also sold two 5wts that never got used, again because I have 4wts and 6wts.
It was a sad day when I realized I couldnt even dream up a rod that I might need. I like the ones I have so much I cant see replacing them
Reels ......that is a whole other story
