I would like to attempt using some Fuji K-series guides to set up some 7', MH baitcasting rods. All will be spiral-wrapped, using two transition guides between the 0 and 180-deg, and a couple will just incorporate a bumper guide. I'm trying to decipher the Fuji guide styles and wondered what model(s) to pick (RV, KW belly, KT...etc.). I normally build baitcasters with a 6, 5, 4, 4,...guide train or similar.

Many thanks for any help - appreciated!

Should have done a bit more research: KW - KB - KT, think I answered my own question!

For a 7' KR casting bass rod, Fuji suggests using a double foot KW10 (or an RV6, which only comes in a titanium frame) as the stripper guide followed by a KW5.5 as a reduction guide. These would be followed by running guides which include 2 or 3 KB guides with the remaining being KT guides all of the same side (I am assuming size 4 from what you said above). By doing a spiral wrap you probably use fewer guides than if you were doing a conventional wrap. The only difference between a KB vs KT guide is the size of the foot, which is wider and longer in the KBs. This supposedly helps to prevent guide pullout due to mid rod forces. The stripper guide is usually placed somewhere from 18"-22" with 20" being a nice average. Hope this helps.

Thank you Norman, appreciated. I'm going to try the KW's for the transition, they have a bit longer bracing than I'm use to but should work ok.
