Hi guys and thanks for the replys. I do shift work so may be a little slow on the reply some times.
It currently getting soaked in Charlie C for 1 hour every 2 weeks which I will push back to once a month in the down season. It gets around 8 hours of Melbourne afternoon full sun after I made a little merbue deck on my second story over the tin roof. Unsure if I should be using Seasol as well?
As far as the style goes, the tall branch on the left was just a sacrifice that has grown a bit long and will eventually be cut. I was considering either like you have said kc or keeping the far right. Here's a couple of virts.

Eventually I would like a nice low canopy along the length of the first virt but I'm still considering options.
Thanks for tour input guys and any further would be appreciated.
Cheers,
Pearcy.
