An astute observation. LOL A few years ago I had reels from Daiwa, Shimano, Pfleuger, Abu, Okuma, Quantum, Pinnacle and Mitchell. A total of 40+ reels to service and maintain. I decided that was a bit excessive, and vowed to simplify.
After decades of working on reels, seeing all the internals and what materials were used, I decided that Daiwa was going to be my choice, and set about selling off all the rest. I got bit by the tuning bug at about the same time, and there were a lot more options available for Daiwa reels than any other at that time, which influenced my decision.
I've been semi-successful in this simplification. I sold all of the non Daiwa reels, and all of the low end Daiwas, but still have more reels, and rods, than I really need. I know, a truly blasphemous statement, but I have rods and reels that see little to no use during a typical season. I have several combos that haven't been out of the rod rack for three or four years.
Now that I've been bitten by the rod building bug, I'll be replacing several of my factory rods with my own builds, and will be selling off rods to help fund this addiction.
I don't think I'll be selling off any reels, except maybe the Pfleuger spinning reels. All of my baitcast reels have been tuned, upgraded and modified. Once I do all of that work, It's very difficult to contemplate selling them. They are "mine" now.
