I do my own stringing and I have heard that people who do their own stringing often buy strings in reels to save money. What I don't understand is how tha saves money. I have done some calculations on a few kinds of strings and found that the cost per foot of string is about the same for prepackaged and reels. Right now I buy sets because it is more convenient for me to just grab a set and not have to worry about measuring out the amount I need. What am I not seeing about why to buy (and keep) strings in reel form?
