Agree with Mimizk try them all is the only way, I have tried 9'10'11' and 13' with 1/2" 5/8" 3/4" for now I am on 13' with 3/4 and even with the 13 my quick turns are still good and this is the best for me. 6'2" 180 without gear, I really like what I'm on now but would be nice to try 14' or 15' if available someday.
