I got to admit but using the PS Storm (non-tour) hit me with the same experience (TE), I just didn't know what was happening. I have SPPP in it and that is a "soft" poly - have left off using it because it was just all too painful and so am prospering with a kB98.
I really wanted to use the Storm, but it's stringbed I found a little less accurate than 18x20s that I am used to...
In addition:
I hoper to go back to it at some point as my TE has receded (though it;s lurking).
I'm just not totally sure that I can blame all this on the racquet. It's had to pinpoint the exact cause of TE because it is perhaps more a combination of factors.
It's too light for me stock so I did add lead. However I just couldn't get it to perform as I wanted.
