i agree gaston, my first experience with rotary machines was the o.g. neotat, but i definitely don't think that rotaries would have gained as much steam if it weren't for guys like Carson Hill and his neuma machine. its all just a continuance of guys like him and the others you mentioned, stigma, and the fly machine, etc. not that the neuma came first but it opened peoples eyes as to what was possible. im amazed and honored be able to see the apex of all that is happening right now
