Need some good suggestions on trying to get some power out of my new 4D 300 Tours. Been using APDC with Cyberflash and Cyberblue at different times. Cyberflash at 45# full setup and Cyberblue at 47# full setup also. Tried same string in the Dunlops but even strung at low tensions of 43# still can't get the power. I know it's a less powerful racket but may have to go to multi's to get some smoke! I'm a legitimate 4.5 and play a power game so I know what I'm doing. Tried Addiction at 50# and still nothing. What do you guys think of dropping tension down to 45 to 46# with a multi known for good power? Would prefer to keep the cost per set down to around $10.00 as I am used to spending only $4.00 per set for the polys since I buy reels. Don't mine restringing often due to breakage. What else am I going to do when watching the Tennis Channel?
