I played with Angell K7 Red with 3 grams of at 3 and 9 with my usual string Gosen OG Sheep Micro 16 at 55lbs which is mid tension. I have say after playing with numerous players racquets over the years that I was disappointed with the playability of the Angell frame. The power level was quite low and the response was very unpredictable! A lot of times I had no idea where the ball was going on my usual swing. Maybe the racquet is string sensitive and needs a stiffer string for better control. The fact that the K7 Red is low powered takes it away some arm friendliness on my shoulder due to swinging harder than usual. The new Blade 98 16 x 19 v7 is a much super racquet IMO in all areas, except for spin possibly.I will definitely be able to tell you since I played with the Becker London for a few years. I agree that it should be a similar but hopefully the K7 Red should have a little more power. I will keep you posted!
The K7 Red plays too mushy with a synthetic with my Gosen Synthetic string and IMO it does not play like the Becker London. The London is a better all around racquet then the Angell frame IMO. It played well with a soft string and had a very predictable response! I would say the new Blade plays similar to the Becker London with the only difference being that the Blade has a bit more power and better stability. Wilson did a spectacular job with the new Blade as the stiffness rating was lowered to 62 and comfort and ball pocketing is off the charts!!
