The Bio 400 Tour with Rip 16 at half tension is the best Dunlop I have tried out of the Bio line and I have tried a lot. Nice controlled power and the Rip String lets you take a nice swing and keep it in play. I had to get adjusted from the the god awful powerful Silk string to low powered RIP, now it feel just right. Great spin and feel.
