So old dogs can learn new tricks

I was out playing this morning with J$ and a couple others. I was told that my thumb pressure was in an incorrect position, and to use my whole thumb lying it flat on the plate(throwing RHBH)for maximim grip and dont "pinch" with just the tip of my thumb. That very small change in grip realy helped keep the disc planted in my hand during my throw. I realy felt like I had to fight the disc less for grip. Great now to brake 20 years of bad habbits!! Thanks J$...
