Mike, I don't think you can say 'without question' if you haven't tested a Waples head back to back in a scientific test with a Karl Norris Head.
What you can say is that in harveys opinion (and therefore yours as well!) Waples does the best heads!
I had the choice of either and wasn't bothered about cost or time and CHOSE Karl.
I am VERY VERY happy with the results
P.S is that the right spelling of chose? or is it choose?
