After some long waiting I got my 2 phantoms from TWE. I bought them blindly after reading others responses here (I have no possibility to play /demo/buy them in my country).
So I thought I'd add my opinion and may be it'll be useful for somebody.
First, some background. My racquets of choice for the past 15 years were PK 5g with some lead at 3,9 (345g weight), and also several 5g PSE (360g and 375g). I started using PKs b.c. I previously played with Prince graphite and developed TE. I had no issues with TE since but, I suspect , my addiction to heavier racquets (and to MTB) lead to very bad inflammation in my shoulder recently. So I stopped playing for almost a year. Now in a search for an arm friendly racquets I wanted either PK Q-someth. or Phantom. I also took a Rebel Exo 105 for testing, and didn't like the vibrations I felt, and a somewhat low power.
Now, here is my mini review after 1h session with a former ATP player (no lack of pace):
1. The only customization I made is I replaced a resipro with a leather grip. B.t.w., the grip size is definitely on a larger side. I played the Rebel in 4 1/2 which was spot on, but Phantom's 4 1/2 feels like 1 size up... It still passes 1finger test, but I may need some time to get used to.
2. I measured my both phantoms weight and balance. Both were 314 unstrung (nice!), and the balance difference was about 4mm between the 2 (is it ok, or need some customization?)
3. Strings setup: soft polys 17 in mains at 22kg and soft syngut 17 at 23kg in crosses.
4. I thought it will feel lighter. Surprisingly I feel it's a very solid , both in play and in hand (my ATP partner said that too after just holding it).
5. Play:
I didn't serve b.c. I feel my shoulder is not 100% yet.
Groundies: very solid, no lack of power at all, spin and flat no probs. I wouldn't call it a put away monster, but I could definitely finish the points w it. Control was also there, unless I was late to prep. Both fh and my 1hbh felt good. There was some less natural feeling with the bh slice though. Volleys were good in general, although a bit not natural, either b.c. of the grip size or balance. Also did a few 'light' overheads and they felt very solid too. Did not feel any shoulder discomfort.
However, there was some bothering thing - I felt some substantial vibrations in the head, especially on my BH side (groundies and volleyes). I need to play more w it, to understand if it doesn't harm my arm.
So, overall, it was a nice first date, but some follow up is definitely required for the final decision...
