I normally use PCG LB (shortened to 27.5) with 3 gm lead at 12.
I am demoing Phantom from TW (got a brand new one with plastic on handle!). This is strung with Prince Tour XC 15L (seems like within 48 to 52 lbs). I played 4 long games with it yesterday. I put it down after 4 games because I thought it will play better with some more weight.
I am partially there with what
@Mac33 is saying. Phantom does have very good plowthrough. But this is not a racket to keep hitting neutral rally balls. My neutral ground stroke swings landed the ball shorter than I like and from defensive position I struggled. Tour XC is too control oriented, so some other string will suit better for me.
But every time I went aggressive with good racket head speed, the speed and depth on the shot was exceptional resulting in outright winners where you can just bit opponent with pace. May be there is a hotspot in this racket. It reminded me of Wilson Pro Staff 97 that I tested 2 years back.
I think Phantom will be great racket with some lead at top (10 & 2 I guess). So for my use I think along with lead, I can extend this by 0.5 inches (Despite 328 swingweight it's really fast moving racket).
Perhaps we have different games?
I think Phantom is better suited more to the aggressive style game.
