What's the difference between the Yonex Armortec 150, version 2007 and version 2008 racket? The badmintonwarehouse.com has the Yonex Armotec 150 2007 version for regular sale price $69.95 and a list price $100.00 http://www.badmintonwarehouse.com/product_p/ryat150.htm while the badmintonavenue.com has the Yonex Armotec 150 2008 version for regular sale price $68.90and a list price $79.99. http://www.badmintonavenue.com/SearchResults.asp?Search=armortec+150 Does that mean that the Yonex Armortec 150 2007 version has a better quality than the 2008 version cause it's more expensive? What's the difference between the two versions? Which version is better? What string tension would be best recommended? Thanks!
