I've only built 6 spinning rods. The only experience I had with spinning rod guide trains prior to building my own rods was on various factory rods that I owned. They either used NGC (new guide concept) guide trains, or COF (cone of flight) guide trains. Both of those type of guide trains use larger guides in their reduction trains. Cone of flight is old school and is more or less one continual reduction train all the way out to the tip top, in that each guide is progressively smaller, and shorter as it nears the tip. A cone of flight guide trains is a straight line to the tip of the rod. Guides are sized and spaced to keep the line running
A new guide concept guide train has what is called a choke point. The choke point is the spot on the blank that a straight line from the center of the reel spool intersects the rod blank. The distance is based on the diameter of the spool. A guide is placed at the choke point, and then running guides continue to the tip of the blank. A cone of flight guide train is going to be the heaviest of the two. An NGC guide train will be lighter, but how much lighter depends on the length of the rod, and the size of the reel. A shorter rod with a larger reel will have less running guides.
With all that said, every spinning rod I have built, I have used a Fuji KR concept guide train. It was designed with braided line in mind, but I can attest that it works better than the above mentioned guide trains on nylon mono filament and fluorocarbon lines. It uses taller smaller ringed guides in the reduction train and works on the principal of rapidly choking the line down to where it is running straight by the time it gets to the choke point. Because of this the choke point is closer to the reel than the choke point would be in an NGC guide train.
A KR concept guide train is going to be the lightest guide train of the 3 mentioned. They are extremely easy to set up using the following link

Open the page and go to the menu box in the top right hand corner. Click on it then scroll down to the Resources heading. Click on the KR guide placement software link, input the information the software asks for, and it will tell you what size guides you need, and give you the placement for the reduction guides and choke guide. Ignore the recommended number of running guides they suggest. It's not going to be enough. I would get at least 1 and in reality, 2 or more running guides than they suggest. Running guides as always are placed using the 2 line static load method.
You will absolutely LOVE the way the rod casts and performs.
I use Tatsu fluorocarbon line as the main line on all of my spinning rods, and they will all out cast any factory rod I have ever used. And with braid, it's just nuts how well they cast.
