Thanks RockyAussie, sorry for the delay. Great info there. I was able to have a chat with Doug. Glad to know there is someone that does this in the country! Never considered that a longer blade might not run as true, but this would makes sense. Too bad Cowboy Australia doesn't have a splitter in between the 6" (a bit too small) and the 20" (a little too big). I am aware the cobra class 14 exists, and seems like a great machine, unfortunately a bit out of reach financially for me at the moment.
