So I am sitting here stringing line on my new reels and putting them on my rods. It occurred to me that some of my rods have large line guides, and some have rather small guides to the tip. I imagine that the smaller guides work better for worm or jig rigs, but I started wondering this: I am starting to use a baitcaster after MANY years of not fishing. Is there any scientific research on casting distance, and how do line guides either help or hinder the distance when using a baitcaster? Does anyone have an opinion on this or experience with these conditions? I have not SERIOUSLY fished in 30+ years, and now I am returning to it. Am I overthinking this or what? I welcome anyone's opinion on this, because I am seriously searching for answers on my gear, before I even hit the water. Here's to hoping I have a season of ZERO birdnesting on my first serious year back to the sport. Thanks.

You’re absolutely overthinking it and we’re here to help you overthink it even more.  Welcome to the forum. 😀

Here is a post about Micro Guides 

Here is another post 

 

Smaller guides weigh less.

 

Larger guides allow leader knows to pass through better.

 

That is the sum total of everything I care about regarding baitcaster guides.

 

There is more science I care a little about when it comes to spinning rods.  Also spiral guides introduce some science, but best not to go there for purpose of your questions. 😀

There all kinds of opinions and theories on the topic but nothing conclusive or proven.  Using the smallest, lightest guides to pass connections and hold onto use preserves the blanks inherent properties offering maximum performance. Do what you will with that.
