Well, it looks like you play 40 to 50 hours a month. Your looking for a string that holds its characteristics for that amount of time. Some of the natural guts like Pacific Tough Gut or even Babolat with its BT7 coating will not only last 50 hours but offer comfort, spin, control, feel for its entire life time. If the tennis shop doesn't carry natural gut buy it from TW (or whoever) and have the tennis shop string it. Labor will cost you around 10 bucks. BTW natural gut is more powerful than most other strings so increase the tension. Like 3 pounds higher than your NRG2 hybrid. Buy 16g.
