I've been playing a golfworks Defiant with an aldila nvs 55R shafted at 46". For me it just reduces the distance loss on off center hits. I think I'm getting more distance but since I'm not that consistent I'm not sure. Since a brain tumor took me out of the game for a few years I would play with a non-conforming bag full of non-conforming clubs if I could and wouldn't give a rat's butt about it.

    Is there a "non-conforming" driver which produces noticeable advantage in distance ?
    Or most of them are marketing slogans !
    I would consider over 5% gain in distance keeping everything else the same qualifies.

    govols Still at it after brain tumor
    Play with any darn club you feel like using !
    This world, the next, then the fire trucks
    ???
    I don't know...

      Release,do you want more distance? Get fitted. No need for a nonconforming driver,believe me.
      Govols ,if there is a non-conforming putter I am ready to buy it if you can tell me where.

        Believe me, I know the importance of being fitted for golf equipment.

        I was asking if there is a real distance gainer regardless of conforming or not.
        The upper limit with current technology and material at hands could produce a COR of .90 So is there a driver head close to .90 COR ? If so, anyone has experience with it ?

          The longest non-conforming driver (it was never submitted) I have ever used was a TourSwing Infringer.

          I finally retired my Infringer for one last adjustable driver vs 919 shootout.

          With an Moi off the charts and non-conventional in shape, it should be non-conforming.

            There is the TPF M80 , the Enhanced model for ss below 85 mph (I think) has a 0.90 COR but still I do not get any more distance compared with my legal drivers.However I have the impression that the Ryoma Maxima D1 (www.tourspecgolf.com) does fool the norm because both crown and sole are made of a propietary Ti alloy that flexes like paper.Great carry and incredibly unusual long roll.

            I am aware of the overseas market for the non-conforming drivers.

            Not ready to spend that kind of money for a golf club...... although I had seen what the equipment could do to boost the gofer's confidence.

            Balleszabal Dechambo ? has non conforming putter he might let go cheap since USGA is on his a $$

              Hit more fairways, your scores will drop.

              So from what I gathered, most of the "non-conforming" driver heads are just... mostly hypes !
              Okay back to work out so I could think that I'm 30 years younger.
