Glad I bought two of them from TW on a whim ! $54 a piece!! It's actually $59.95, but I got additional 10% as I ordered some more stuff! Currently, I play with IG Radical Pro and am happy with it. But when I saw this deal, I couldn't pass up. I had tried AG100 couple of years back, but, for some reason, I didn't like it at the time (probably, my game was not up to it). So far I am liking 4D100 a lot, so much control, not too harsh on the arm. My serves are more accurate and picked up more speed! Volleys are lot better, can feel the ball. Based on what I read on the epic AG100 thread, I have added lead 1gm@12, 2gm@3pm and 2gm@9pm. Strung both racquets with TourBite 17 mains and Forten Sweet 17 crosses. One racquet at 53lb mains/56lb crosses, second one at 48lb mains/52lb crosses. Haven't tried the lower tension one yet. I am pleasantly surpised, especially considering what I paid for this brand new, quality player's racquet! What can you buy for 50 bucks? Go for it! It's a STEAL! Don't be afraid of 90 head size!!
