I tried the new PS6.0 85 from 2011 batch and compared to a 1987 St Vincent-frame with same setup as the 2011 (strings, grips, tension etc) and the St Vincent feels a tad more solid, more crisp.
For my game, the PS 85 was not working well and I play much topspin with a western grip (wanted to buy an Eastern-grip but found no for sale,,,

) I´m not a rookie or anything, I presume my NRTP is something similar to 6.0 (i have a decent national ranking here in Sweden) but I play so much better with a frame with bigger headsize. I also had one of my hitting partners, a guy ranked 50 in Sweden, try the racquet and he used to play with that frame when he was younger and he said it was nice and all, but that the frames of today gives much more help and equal power and control.
Sure, it´s not the scalpel-feeling in the +95 sq inch modern frames that it is in the PS 6.0 85, but overall, a modern frame feels (for me atleast) better in every category then the PS 6.0
this is from Hankenstein's blog translated from Swedish to English using Google Translate:
What has Pete Sampras, Jim Courier, Roger Federer, Stefan Edberg, Chris Evert and Mary Pierce in common? Difficult, is not it! The common denominator for these players is that they all lirat with one of history's most classic tennis racket. Wilson Pro Staff 6.0 85
This amazing success bat saw light of the world the first time in 1982 in Illinois, specifically in the Wilsons River Grove factory. The first Pro Staff actually had a 110 square inch large face but realativ soon as it produced even in the 85 sq.inch and the entire 125 sq.inch. The bigger hit areas were phased relativit quickly out of production while the 85 sq.inch large clubface survived along with a 95 sq.inch big brother.
The player who made Pro Staff 6.0 85 best known is Pete Sampras, who throughout his active career retained the original design from 1983. Widely known is often hears that many pros are using an old design, but with modern painting, but Sampras was so delicate with his equipment that he is not accepted in other than original design. Pete was faktistk so sensitive that he even demanded that they used a minimal amount of paint as they painted the red Wilson logo on the strings, unless this was the balance of the racket wrong. Now we speak thus slightly half a gram in weight ...
From 1984 to 1991 made the Pro Staff frames in a factory in the Caribbean, specifically in St. Vincent & the Grenadines. Here was working extremely closely with their craft and they were competing internally over who received at least wrong with it the manufactures. It was therefore almost no limits were rejected in the production and quality was extremely good.
However, it was one thing that made them St. Vincent-made frames unique. In time, forms the cast frameworks in the worn and not quite closed tightly during the "baking" in the oven. That's why frame widths 18 mm instead of the original 17 mm. This seems in any case, Sampras was very important and when the factory closed in 1991 so he vacuumed (or rather some poor Wilson) Market at St. Vincent-made frames so that Sampras could sleep peacefully. Although Jim Courier did the same thing, but on their own, and in their garages learn there may be a couple of boxes new St. Vincent-frames.
On the various forums and auction sites around the world have these rackets have reached almost cult status and secondhand price is between 250 and up to $ 1,500 for Used bats .... Crazy! Wilson, however, realized that there was a pent-up need that guy all over the world want new Pro Staff 6.0 85's to play with and have therefore produced an edition of them again, according to the original recipe from 1982. The first edition came only to the U.S. and sold out in two days. Now they have released an edition and also the start to go into the reserve tank already, after only a few weeks of sales.
Course was a material guy that I just had to buy me a bunch of the new framework, mostly just to get to know the history. In order to compare with the original from the mid-80s, I had to borrow two pieces St. Vincent made Pro Staff 6.0 from 1987 by a good friend of mine. Happily and with half-broken wrist I went out into the valley in Taberg light gray rectangle with an emerging Wilson U.S. Open balls and began to feed baslinjeslag ....
First, we knew the original from -87. An overall very heavy bat, but most part of the weight sits at the bottom of the grip and therefore felt it is not particularly heavy when you swing it. The first meetings went on pure inspiration. BOOM BOOM BOOOOOOOOOOOM echoes in the hall when a day of exclusive eastern grip feeder straight before the event. The meeting is centered in the small sweetspoten and precision is like a scalpel in the hands of a skilled surgeon (get me right now, I'm not anything but a happy exercise, but when you meet the right with the Pro Staff 6.0 so fly ball exactly where you like)
Quickly switching to the newly framework and here you notice a difference immediately. Sure, weight, balance, etc. the same in the two frameworks, but the elderly are somehow more pure in feeling. The newly probably would all do well a little lead on the sides of the face in order to stabilize it against any miss-hits.
The test continues with regular exchanges between the generations and it is just that little bit little that separates them. Barely noticeable, but the older part is a little bit more stable in a sense. If it is that it has lost its original stiffness and better parry my little miss-hits, or if it is 18 instead of 17 mm wide frame, or if it is different for graphite / Kevlar materials 1987 to 2011 I do not know, but a small difference, it is in all cases.
Who is it one of these classics can fit into? Are you a baslinjegnetare as beaters before hand with an extreme Western grip which may Berasateguis forehand to act normal, and a Rear weight which had automatically made you a champion in Limbo that is not the Pro Staff 6.0 is for you. However, if you take the ball early, playing more traditional and hits the ball relatively flat and want to have good control, then these newly produced 6.0: or fit your game. Serve and Volley is ridiculously stable with this bat and the weight of the frame enables you to have a very heavy serve.
Will I continue to play with this framework? NO! I am unfortunately that limbo dancing dude who has a grip like Berasateguis and it feels not quite right with this racket ..
Well, that's right ... If anyone is hungry so I now have three pieces of these for sale. Two pieces completely new, even more stringent and a pc with a multi-stranded filaments late and in mint condition. Grip 4 at all three bat are.
MERRY CHRISTMAS!
