can you describe to me the difference to you?
The phantom feels more plush. I bet I'd like it more with a similar high tension string job.
Well, I agree with what
@Addxyz has said. To that, I will add that one racquet is very thin beamed, has a box beam, has a lower RA, is much more control-oriented, low powered, and is a precision scalpel (Prince Phantom Pro 93P); the other is a thicker beamed, stiffer, more powerful, less precision and less control-oriented (in comparison to the 93P), non-box beam weapon (Wilson 6.1 95).
The Phantom 93P needs a looser string bed to provide some additional power, so I personally would not string it tight. The ball dwells on the string bed much longer, and the feel is plusher in comparison to the 6.1 95. Both have precision, but the 93P is the more precise of the two.
The 6.1 95 has easy power and a great weight-of-shot, it has a more direct feel and a great balance. If your technique and footwork/ fitness are good, you just need to get out of the way and let the 6.1 95 do the rest for you. The 93P requires much more involvement from the player.
Hope that makes sense.
