How sad to respond to my own post (awww)
I suppose that no one else has a view on my bamboo.
Although I have not found any advice on the net, I am just going to do it anyway and remove all of the new shoots that I think will only be cut out later.
In my mind the roots will use less energy and may redistibute this either this season or next season.

Surely I cant be pioneering this approach HAHA! surely not?
