I am going to be building rod for my buddies. One will be a 7 foot 3/4 weight the other will be an 8'6" 5/6 weight. They want to use single foot wire guides. What sizes should I use? Should I follow the chart for the sizes for snake guides or the chart for single foot guides? Why are the sizes differant in the charts?

The chart for the 8'6" says snake guides = 2 2 2 2 3 3 3 4 (12) and the sindle foot chart says 3 3 3 3 4 4 4 4 (12)

The chart for the 7' says snake guides = 1 1 1 1 2 2 3 3 (12) single foot = 2 2 2 3 3 4 4 (12)

Thanks.
