Racquet and arms pain

 This three powerful racquet gave me sore/pain in the arm areas, they are:

• Wilson Pro Staff 97: wrist pain on off center hits (may need softer string tension or thinner gauge)
• Head Radical OS: thumb pain from backhand (may need to replace leather grip with regular grip)
• Dunlop Aerogel 300: pinky finger digit from racquet shock (changed the leather grip to regular grip, will let you know of the result)

 Low powered frames does not give me arm pain but they are low powered (Dunlop CX Tour, Dunlop 200G, Wilson Six One Team).
