    When you string a racket and then when you cut it out after its dead or when you want to change it will it still have its original shape? or would the shape be different?

    To clarify.
    After it's strung for say... a year. You cut the strings, and it could possibly be off by 1/8th inch, or slightly more, but will go back to it's original shape within a day or two. This for carbon fiber rackets.
    Wood rackets take longer to get back into original shape.
    Aluminum rackets can stay out of whack foreever, or until the stringer makes a conscious attempt to straighten it.
    I worked with carbon fiber and composites, making motorcycle fairings, seats, car spoilers, surfboards out of carbon and glass composite structures.

    Does graphite loose it's shape?

    Graphite doesn't lose it's original shape, it can deform into more of a circular or a narrower ellipse shape if you don't bolt it down hard enough to the stringer though. Though it will go back to normal when the strings are cut out.

    Carbon graphite retains it's shape only as well as the structure around it. There are no solid carbon graphite rackets.
    Even 9 layers of 9 oz carbon, used as a spoiler on racecars, take a semi permanent bend over time, depending on the loads it was subjected to by the wind and by the way it's loaded on mounting.
    Maybe we should grasp the notion...everything changes over time.

    A racquet will change its shape from its original purchased shape after years of stringing and playing, though its negligible. I was just saying to the OP that he shouldn't worry about the shape of the racquet after the strings were cut out of it, no one would notice the difference. Unless of course that person is really picky about a few micrometers or even millimeters off, then I would suggest a therapist. :)

    Edit: I put Of course in front of the start of sentence, made me sound like an ***, sorry about that I didn't mean to offend you.

    OP, do you mean that if you've deformed the head shape slightly ( I have noticed this on the Speed and Radical lines recently) into a circle, will it return to its more oval shape once you cut the strings out? The answer is yes they do. In the examples above, I'm talking about just like 58/58 synthetic gut in a Speed Pro. I actually picked up a Speed MP yesterday to demo and found the same phenomenon right in the pro shop. Dunno why that is (it's obvious why, but why only those frames exhibit such obvious shape change).

    Add the Prestige to that list as well. You have to have a very good mounting system (not 2 point), and even then it's not a guarantee to work.

    Yes it will. For some reason, the newer Head racquets are curiously fragile yet strong. http://youtu.be/JMBqPbLrZMA?hd=1&t=3m45s This video really surprises me as I would assume the shear strength of poly would be much much lower than for carbon fiber. Perhaps not.

    As I was told yesterday by a pro shop owner some 30+ years in the business, the reason the newer Head sticks must be strung 2 piece is because apparently, under bottom-up 1-piece jobs, some frames have simply collapsed even if you do 6-point mounting.

    Take what I said about the one-piece stringing with a grain of salt, because I am not vouching for that statement. That is apparently what he was told by his Head rep.

    You should also try to figure out why its warping so much. It could be faulty equipment, poor stringing technique, mismatched mains/cross tensions. A proper string job shouldn't warp the racquet.

    Also, you shouldn't play on a racquet that is warped out of shape. That can cause permanent damage

    Deformation and warping are not the same thing. The Speed Pro is near circular once strung, but is still elliptical unstrung.
