gnat,
I'd call the manufacturer and get the guide spacing for that particular model to start with. Also may have to do with the design of the ferrule. Check out the pictures on the Scott website, looks like they put guides on the female ferrule on their rods. I think at least sage and winston put guides near the female ferrule too but seem to think they're about 1" to 1 1/2" above the end of the section.
good luck.
