Stiffness of AK90 - anyone put one on an RDC?

    I'm curious to know the RDC-measured stiffness of an Asian K Factor Tour 90 (AK90). Posters have compared it with the US K90 in old posts - some say it's about the same, others say it's more flexible. I think it's difficult to compare stiffness when the frames are so different in static weight and swingweight.

    Has anyone put an AK90 on a Babolat RDC to measure stiffness? Or does anyone have the RDC + AK90 to do it?


    Short of that, AK9/USK90 users now have several years of play with these frames. I'd be interested in hearing any updated impressions of how these frames compare in terms of stiffness.

    In my experience, Japanese are always more flexible than Americans:twisted:

    I had my AN90 measured on a swingweight machine (NOT RDC) along with a RDS001 mid, the AN90 measured 69 and 001mid 68. There is 1 point difference and that sounds about right since in TW specs, a N61 90 is 66 and 001mid is 65. So its safe to conclude there is no difference in stiffness between the Asian N61 90 and US version.
