Well, what if Babolat VS (BT7) lasts 50 percent longer than Klip Legend. So thats like adding 13 bucks to Klip Legends price.
So your spending 39 bucks for Klip Legend when compared to VS gut.
If you factor in performance then Klip Legends cost increases since VS gut out performs Klip Legend in every category.
Keep in mind I find VS (BT7) to last twice as long.
