I love Dunlop racquets, but I cannot stand their inconsistent use of terminology. It is damned confusing. Tour--does this mean a heavier racquet? With the 200 Tour it means 12.5 ounces, with a more open pattern of 16 x18. With the 300 Tour it means 11.3 oz. but a denser 18 x 20 pattern. With the 500 Tour and the 600 Tour it is 11 oz. Is 11 oz. heavy? Lite--does this mean a lighter weight racquet? With the 200 Lite it means 11.5 oz. With the Bio 400 Lite it means 10.1 oz. With the 400 Lite it means 10.1 oz, with the 600 Lite it means 10.01 oz. Do you consider 11.5 oz. "Lite"? Plus--does this mean a longer racquet? All the other Bio 500s are 95 sq. in, but with the Bio 200 Plus it means 100 sq. in. and standard length. With the Bio 500 Plus it means a 110 sq. in head and a 16 x 19 pattern and standard length, but the Bio 700 is 110 sq. in head 16 x19, 27.25 length. Aarrrggghhh!!!
