well.. after a cpl of recent games with newly copper plated heads I gotta say there is a noticeable difference in feel, they are most definitely softer, and the ball seems to "stick" to the face more.
although I cud see no noticeble difference in performance , ( I don't think that the point anyways...)
but for feel........., oh yea.., they are really fantastic which is a really nice thing in winter.
even the reflective glow from the sun isn't an issue. which I thought I might be , but nope.
gotta say if uve got a set of special heads.. getting a GOOD plater to re do them is a fine option if u like soft,
