and I thought about a different type of hurling which I dabble in....

the catapult/ trebuchet/ballista crowd refer to their activity as hurling as well. I have a little one for hurling golf balls [36" arm] in my dinning room

"the" link is here:http://www.trebuchet.com/

It sounds like you are talking about something similar to an atlatle [sp?] or Jai Alai?
