Yo, my suggestion is to wing it, bend 'er down and seperate the shoots with some lst. From there, fim the tops but not too many at once. I don't fim but i have topped. Give it a whirl and lemme know how it goes. Honestly with the amount of tops created just from bending alone, i wouldn't be worried about fimming for even more but hell, the more tops the better! lemme know what you decide to do, maybe a pic too!
