I see there are 2 different makes of the Prince Precision Equipe Midplus. One says "Straight Beam" on the racquet head, while the other version says "Straight Shaft". The throat with the "Straight Beam" also feels glossier. Other than that, they look the same. Is there any real difference between the 2? BTW, I don't think this is as much a clone of the Wilson PSC 6.1 as it's supposed to be. It seems stiffer and has a 16x19 pattern vs 16x18 of the PSC, with the 16x19 of the Prince producing noticeably better control. I haven't yet tried the 18x20 PSC, so would like to see if that compares better.
