I forgot one little bit on the update. The toolholder / change operation is a little more touchy than the HSD.....some of the internal on the tool draw bar I think are not as smooth and I have had to modify my posts (the part that gets pulled on) to be a touch more rounded that they were (I had some that were more rounded from the factory), and upgrade my tool forks to be more rigid and do a better job of holding the tool straight up and down (my ATC is abnormal so not regular forks for me, DIY unfortunately)
