Hi Dusty,
Eary last year there was an article in the press re this new cycle that Monash were trialling. they spoke to Gab Kovacs as he is the "boss" and it seemed to say they were hoping it would be used as standard fairly soon. It sounds exactly like what you are describing and they said it was a down reg cycle but with less time on the pill.
Just for my own interest I spoke to my FS about it late last year, as we are with Monash and I wondered what she thought about it. she basically said it would have to produce consistently better results than a down reg cycle and it had not yet done that so they weren't changing.
Sounds like it would be a good thing for you as you don't respond well to down reg. - you may as well try something new. Dr Kovacs has been doing this along time and I have heard some great stories about him and he has been very nice the few times I have seen him. (saw him as a public patient when first being investigated for infertility) so I think you are in good hands.
good luck
