I took a 10+ year break from the sport, and I feel like that gave me a unique perspective on how far and fast the technology of gear changed within the sport from the early 2000s......and then from the 2020s.
For the most part I only buy Made in Japan reels, so the reels before and now would be considered the higher end models from both Shimano and Daiwa. Reels like the Calais and Steez from the early 2000s, and reels like the new Zillions from today.
What I learned is that the differences b/t early 2000s and 2020s reel technology is not nearly as significant as most other aspects of the tackle markets. I don't feel like a Calais or Steez from 2007 era is all that behind the Zillions of today in terms of tech and usage. For me I feel like reel technology evolves extremely slow, with very small incremental changes happening to them.
On the other hand, it's beyond mind blowing how much both hooks and lines have improved. The hooks and lines of the early 2000s are no longer usable for me given the massive gap in effectiveness and tech in the current ones.
Look at lures innovation from the early 2000s to now......insane. Whole new categories of baits like Glides, A-Rigs, Jighead Minnows, etc.
Look at electronic innovation from the early 2000s to now.....beyond insane. Literally real time tracking of fish using sonar.
The thing that has changed the least from the early 2000s to today is reel technology.
Like the AR-15, the modern day Bass reel has been refined to death, and any technological advances are happening on such a small scale year to year that's its hard to notice.
