Every year, the routine question of, "What is the best..."
People ask this all the time and it's 99% opinion and 1% actual best gear.
There is a lot of factors that involves in what is best. What is best varies from person to person. The best materials may not always be the most advance material. E.G. graphene is probably the most advance material to be used for a fishing rod. However to produce it in a long enough strand that is material consistent for a 6' or 7' fishing rod blank, is currently not technological possible in a cost effective way. There was once a time when Boron element fishing rods were technically the best fishing rods. Well it seems nonexistent in today's current offerings. I'm sure if I research on the internet, I will probably find the reason(s) why not.
There is also different concepts in fishing rod desinges. E.G. Wavebuster line guide trains concept. It's sort of a concept that if the fishing line is immediately choked into a straight funnel it should flow better and cast further. However does the physics stand behind that? Sort of depends where one is examining it.
For a while there was this push for larger spools on spinning gear will cast further. Yes a narrative concept on that sounds great and very convincing. In fact it does work to a generalized concept. However the nuances and the specifics don't always work out. The consumers and user just went back to small reels with small spools. Becuase mechanically it's just works very well. For one sample comparison of a Stradic 1000 reel with a 40mm spool lip vs a Sustain 1000 reel with a 39mm spool lip. For two nearly identical reels in mechanical designs and even possible interchanged parts, theh Sustain reel may have a few more bearings in place of bushings and some better material on parts. Yet when used the Sustain reel casts so much more smoother and less effort for distance. That difference in just the spool lip diamter of 1mm seems to play quite an influence on the overall feel.
People...alway s someone will asks, "I want the best..." then says, "I will only pay $50...or even $100 for it." Sometimes the concept is really just asking for the best garbage gear. Yes, it can be the best gear for one season of use, basically a few months. Whereas most of them are not actually looking for an heirloom type of gear. Think about that, something that can possibly be past down to the next generation or more.
So in the end, what is best opinion. Just fish what you like.
