Both sticks are 98. Both are between 10.8 and 11 oz. strung weight. Both have about the same beam widths. The Storm has a 3pts headlight balance and the 300G has the 4 pts. headlight balance. The Pure Storm has a slightly higher swingweight (312 to 305 or approximate) What are the differences? I used to play with a 300G and loved it but felt it lacked just a little bit of "pop". Does the Pure Storm provide that slightly extra power while still being as maneuverable (very important to me as I can't handle the heavier player sticks like I used to)? Also, what is the best guage for a Pure Storm? If I want to maximize power, is the 17 guage better? What's the best string for the Pure Storm. I'm a 5.0 power baseliner, one hand backhand and semi-western forehand with a pretty big serve and solid slice. Thanks for your help!!!
