I do not have that rod, so cannot give you measurements. What I would do is use the info that you got from St Croix on the guide placement and tape the guides to the blank. Attach the reel you intend to use with the rod and then do a stress test to see where you might need to move a guide or two, or even add or remove a guide altogether. After you feel the guides are in the right place, take some test casts in the yard to insure all is right before you wrap and epoxy the guides. Each blank is a little different so using an existing formula may not give you the best lay out.
