I remember readng somewhere about stringing methods but unfortunately cant remember which thread. I noticed that my rackets have different number of knots. 1 of my MP90s and cab 21SP have 4 knots while other MP90 has 2 knots and my Gosen has 1 knot. I go to two different stringing shops and I guess the stringers there have different stringing styles and methods. I do not know which is better (all my rackets are now strung at 24/23), 4, 3, 2 or 1 knot? Will they affect string tension and maintaining the tension? Anyone care to share? Thanks!!!
