I am fairly new to stringing and have never really prestretched string before. I use Technifibre NGR2 18 guage which probably should be pre-stretched. I am curious how you guys do it? I am assuming it involves wrapping it around something and pulling? If this is the case what do you guys use and how hard do you pull? Do you pull with all your might or just half stength? I just want to make sure I don't damage the string in any way. Thanks!
