Monster Leather

[dbmtrman]

I have a huge leather that is about 18 to 20 inches in diameter. I want to propagate it, but am not sure how much I can cut off. Is cutting around the disc a valid way of making the leather smaller? I have seen videos where they cut the leather right down the middle, through the head and stem, and it still lived. Just not sure I could do that.

It definately has outgrown my 120. Suggestions on how best to go about making it smaller?
