Hi Brett,
It's my understanding that if it's not in the building intructions, it's not allowed.
Before doing anything that is not in the building instructions, I would consult the National Technical Officer of the NMCC, Tim Shepperd.
I think you will find that canting is not a new idea to Mossies, builders have been trying to push the rules on Mossies since the 70's most things have been tried by somebody at some stage, but many learnt the hard way that they where not allowed.
