Well, color me ignorant! I did not know there was a 23.5-inch Fiskars available! That would make the swinging a LOT easier! Even the X-11 might be a good idea.
Thanks, guys... now my Xmas list is complete.
My apologies as I just realized you had a challenge most of us do not face. I would agree that the X11 or X15 would most likely be a good choice for your requirements. The head design on the X series Fiskars is engineered very well and performs great.
