I'm starting to build my forth fly rod. On the previous three, I had no problem getting the manufacturer's recommended guide spacing. Not with this one, however. I've search for general guide spacings until I confussed myself. I have two different tables and two different calculators. The calculators require that I already know where I want both the first and last guides! I would think that the placing of the first and last guides would be the critical decissions. Anyone know how to make those choices or have any other advice?
