The last rod I built for myself I used 0 double foot guides. The largest guide I used was a size 8 ring fly guide, and the rest were size 6 ring fly guides. (all fuji alconites) The blank is a 6'6" shikari II mh. I have the first guide at 0* a bumper at 90ish* and the rest at 180*... it casts as well or better than any of the other spirals that I have made which use a slower transition.
To answer Huck's question, I would remove all of the guides because, like Mattman said, they would be high frame "spinning" guides" which keep the line farther from the blank. I would go with the smallest guides that you feel comforatable with using, and go with the simple spiral like the dude recommended. In my opinion, this would give you the best results. Are you planning on applying a casting/ trigger seat or leaving the original seat on it?
