I don't mean to hijack your thread, butI've been considering topping mine (pics from today in the last page of the link in my sig), and I wanted to get an opinion on it too.
I'm up to my 6th node right now, and here's how they grew:
Node.....Fingers per leaf
..1................1.........
..2................3.........
..3................5.........
..4................6.........
..5................7.........
I've been waiting for it to get up to 7 fingers per leaf before I topped it, but I wanted to get a few opinions first.
