I hit with the Ripstick 300 for about four hours today (fh, bh, volleys off a machine, buckets of serves, and w/someone for about 30 min at the end). I strung it up the night before with Confidential 17 at 52 lbs. As I'm used to the Pure Strike Tour at 12.2 oz, the Ripstick feels so light at 11.3. While it felt solid on forehands and backhand drives (with a little extra spin & launch, but was able to flatten it out), the light frame feels a little whippy to me at times. To counter this, and for maybe more controlled power, I might add lead tape at 3 & 6 and behind the butt cap. While my serve is slow compared to the past (only in the low 100's right now) & I'm working on getting it back, I was surprised I seemed to have less power on my serves compared to the Pure Strike Tour. I was hitting up to 107 last week with the Tour but just 101 max with the Ripstick. However, the Ripstick seems to help with spin/kick serves as I did get some good action on the ball. Maybe, that's why it was slower (or it could be my radar gun. lol) I did feel I could rip some pretty solid fhs and drive some nice topspin backhands. You can definitely hit some good slice backhands with this stick. I did feel it lacked a little stability when dealing with high backhands at times. It could be me not used to such a light weight. Adding weight might be better for serves (for me). With the O ports, this frame might actually be better with added weight and the O ports could still make it a speedy at the higher weights. I'll try to bump it up to around 11.7 oz. I'm also wondering how poly at lower tensions, like 48 lbs., might play. It might be good for returning
