With a smaller sweet spot than a lot of tech heavy racquets, this RF 01 is nostalgic. The sweet spot is smaller but the racquet is far more rewarding with proper technique. I added Tungsten tape at 10 & 2 to help expand the sweet spot in the upper hoop along with adding 9 grams in the handle. A very stable yet whippet racquet. I'm a 1 hand backhand who also slices, my game has enhanced. Wilson knocked it it of the park!
