Hi i was thinking of restring my nano 77 with bg 80. BUt the problem is m not really sure how much i should put on it. I had 23lb with bg 80 before n it didn't give me the power i wanted. Should I go higher or lower? Thank you
it's all personal preference... one person could like it even lower, another higher. I personally use 28 - 30lbs for everything.
You need to know why it does not give the power. Is that your technique? Or, if you are sure it's the string tension, how did you feel? Too loose? Or, way too tight / stiff? All different answers can lead to totally different solutions.
