I've been playing badminton for 2 years, and I am still pretty new at this game >< I currently have my MP Limited (supposedly MP 99 with another paint job) strung with NBG 95 at 25 lbs both ways. I think it has been strung for 2-3 months, and it feels like its around 23 or 24lbs now =\ I found that some days, I can play REALLY bad with it (when I clear it feels very weak and dosen't make sounds) and some days I can play better than I ever thought possible. My smashes could explode sometimes on better days, and worse days it feels weak. I thought that the higher the tension, the smaller the sweet spot, and I also heard that NBG has a small sweet spot to begin with. I was playing tonight, and during the first 3 hours I could barely clear properly, and during the last game I felt confident with my smashes. Might sound confusing, but does anyone have any advice? I was thinking about restringing my racket with NBG 95 at 24 or 23 lbs, or maybe switching to BG 66 with 24lbs.
Search is your friend~ First of all, racquets should be strung at the difference of 2 lbs, mains to crosses (eg. 22x24 - mains x crosses). Sleep and proper training should be considered as important factors to your performance. Best to consult a coach if you're planning to get better and serious... I'm surprised that fir 2 years, you've never considered a coach...
