Yeah, I'm sure his rackets are different from the retail in weight and balance.
From the pictures from Priority 1, it can be seen that long 1/4 inch strips of lead are stretched from almost 10 o clock to 2 o clock.
Say the strings are about 15 grams and also the grip counts for weight, which means on stock rackets, there's room for only 2-4 grams, which is not what is shown in Fed's actual rackets.
