OK take a 7136 rod any 7136 rod. Multiply by the number of manufacturers. Now multiply by the number of different lines, floating and sinking. Now multiply by the number of possible tips. And lastly by the number of different style flies weighted and unweighted. Buy them all and try and find the perfect set up for your casting style. How can the average person possibly do this unless their name is Bill Gates? Just an observation from someone who reads "what rod and reel should I buy before I learn to cast and fish 2 handed".
