I have just finished the modifying the racquet and swung it around the house. By doing just that, I can feel the gap has definitely closed between the two racquets. There is a small difference between the two but I'm looking optimistic about my results on court with the leaded up exo tour. Obviously the string pattern and head size will play a role in how I go when comparing it to the diablo but I think it will be something I can get used to knowing my wrist will thank me for it. I will come back with results when I get on court in 3 days time. Thanks jonestim!
