http://www.tennis-warehouse.com/reviews/LUX4G125/LUX4G125review.html?from=recruit Here is the very favorable review from TW playtesters. Most love the feel and control of this string. but when it came to power, it was a bit confusing. Jason felt it had plenty of power and felt it was one of more powerful polys he tested. but others felt, it was a bit under powered.
