I barely string my rackets and is new to it really i recently got the amp 90 and the only strings i've played on with before is bg 65 which seems very plain i strung it at 25 pounds and my shoulders been hurting for weeks now i want to restring it and this time i'm prolly going to try 23 i was wondering what fits amp 90 the best bg 80 bg 66 or w.e
The type of sting is your choice, give them both a try. BG-80's good for power, and BG-66 is a good control string though it also has good power ( not as good as BG80). http://www.badmintonforum.com/vb/attachment.php?attachmentid=7206&stc=1&d=1105288931 http://www.bbeshop.com/yonex/tech/images/chart_string_2004.jpg
The AMP90 is a stiff racket. If your shoulder has been hurting do not use BG80 as it's a stiff string, go with a softer string like BG65 or even softer, Ashaway MP, PG or ML.
