    Can anyone tell me the swingweight and pts. HL this racket is?
    Here are the following specs: 12.1 ounces strung, 32 cm balance point, and the kicker - 28.5" long. TIA

    The Swingweight could be almost anything. It's not possible to attain from that information. It depends on the polarization of the racquet.

    The balance is 13.2 points HL.

    I had a D+ in Physics, what's "polarization" of the racket?
    Thanks for the other info.

    How spread out the weight is. Theoretically, if you were to have a ball halfway up some weightless string, then you'd have a polarization of 0. And if you were to have a racquet with two balls on the ends of that weightless string, you'd have a polarization of 1. Anything in between is more normal. Generally, higher polarization, higher swingweight.

    polarization simply means the weight distribution, a polarized racquet is one with an even balance and a depolarized racquet is one with a hl or hh balance

    amones right that its not possible to determine the swingweight based on that info, but id guess that its around 310? maybe

    Just a guess. Could this be a Prince ThunderBolt (red and black cosmetics, late '90s)?

    Except I don't remember its balance being that HL...

    To be more specific, using some rudamentary plugging-in and such, I found that the range of possible swingweights was 165 to 465. So anywhere in there's technically possible.

    The racket in question is a Dunlop Revelation Superlong +1.50" (110 sq. in. Oversize) - circa 1997.
    The racket is a factory 3/8 grip that has been built up to 5/8.
    I think I added about 0.9 ounces of weight to the handle and maybe 0.1 ounces of lead just north of 3 & 9. I believe the stock SW is around 330 with a weight of about 11.1 ounces strung, but I don't know what the original balance point was.

    Wow. That's some modification. I might be able to get back to you on that in a few minutes.

    With your given specs, sounds to be roughly 350 kg/cm^2.

    You just have to admire people like Amone who know this much about racquets. Or anything else for that matter, it shows a whole bunch of dedication.

    the specs for the Dunlop Revelation Superlong +1.50" is 314 grams, 340 swingweight, 8.5 pts head light.

    you can find specs for most discontinued racquets at www.racquetresearch.com

    Based on those specs and your modifications your setup has a:
    swingweight of 345-347(depending on where you put the weight in the handle)
    balance point of 12.58 in., 13.36 pts. head light

    you can calculate your specs in the future by using Steve H.'s spreadsheet which can be found here:

    edit: added wrong, fixed it
