well, it took me long enough to find out why i wasnt making as much power as i should have with my MP99. seems the string has lost tension to the point where its below 20lbs. i kinda suspected something was wrong, when i could do full court clears with my cab8200 more easily. i know this also cuz tonight i compared it to my cab strung at 20lbs with BG70, and it still feels as stiff as the first day i brought it home. so i remembered my friend is offering to string badminton rackets. now hes no noob, cuz he strings his NS9K type X on his own, at 23lbs. he hasnt strung it once or twice.. he's string it several times. he uses a drop-weight machine. i know stringing a NS9K is harder than a conventional string pattern, cuz of the extra grommet holes. i have played with his 9K, and looked at the stringing close up. its pretty good, and he does get the tension right. hitting ur hand with 23lb string actually hurts :/ so i called him and he said he has ashaway micropower. i thought great.. always wanted to try that string. i think before he's strung his other rackets himself.. which include a SOTX Woven 5A and an Iso Swing power SX. so should i?
