    Will stringing a 63 RDC stiffness, 98 sq in frame with a full poly at 53 tension allow the frame to play like a 70 RDC stiffness frame?

    I see where you're trying to get to. But your question isn't complete. You need a bit more at the end:

    Will stringing a 63 RDC stiffness frame with full poly at 53 pounds allow the frame to play like a 70 RDC frame strung with X at Y pounds?

    But even then I don't think there is an answer for you. I'm not even sure whether the frame stiffness or the stringbed stiffness is a bigger factor in the "total" stiffness of the racquet/string system.

    But here's a question for you that might lead somewhere: What quality of the 70RDC frame are you trying to reproduce in the 63RDC frame?

    Excellent questioning skills there Corners!
    OP - There may be other ways, possibly more sensible and viable, to achieve the result you want.

    Nice post corners, as usual. I have a related question if the OP doesn't mind: If you string at very low tensions (e.g. poly in high 30s), would that to some extent mask the flex of the racket, i.e. would it make a stiffer and a flexier frame feel more similar than strung at high tensions?

    Does the racket have a 16 main or 18? I have found that makes a big difference in how stiff a stringbed feels. I don't see how full poly at 53 lbs. is going to make a racket feel more stiff, to me in a 16 main racket that is low tension and it will feel soft.

    you cannot compensate frame stiffness with stringbedstiffness.
    just think of the dynamics implied with ballcontact and stringbeddeflection and then think of it as a system. the softer stick with the tighter string will produce a completely different deflection of both stringbed and stick than the stiff stick with the low strung stringbed.
