Take stock head sizes only as a broad guide.
For example, I measured and compared my 4D 200 Tours and PSGTs, both unstrung. The hieght and width of the frames is the same. The PSGTs simoly have a lttle more space in the bottom "corners" and play like a more forgiving version of the 95" 200s.
Instead of thinking of 95" vs 98" think...
Only on Talk Tennis can you find people who believe
that 10 feet of lead tape has no effect on a frame...
