First - If Doug or Harry see this they can answer but other than them, and perhaps Tom, none of the regular posters here had direct contact with Bertholy and have Bertholy's Swing pipe. The swing pipes we have were our developments and not Bertholy's. Bertholy's swing pipe was not symmetrically weighted and that lack of symmetry was used to enhance certain exercises but I've not seen any documentation on the details of the weighting.
Second - The 'swing' pipe was not intended to be 'swung' (unlike Gary Player's heavy club) unless you'd consider this exercise to be a 'swing'. It was intended to be largely a 'prop' that would allow you to get into the proper positions that you would with a golf club and a weight for strengthening the lead arm and wrist for release/post release in some exercises (as shown by Harry Mapp in the drill).
