Thank you to everyone for all the advice.
A new saddle is not an option, but I do think that it is very smart marketing that the Australian saddle gives you the choice. When I talk about give, I don't mean enough that my saddle can fall off, it was more about the horses comfort, which in my mind, relates to more freedom of movement. I had not seen the Cashel off billet and will definitely be looking into that. I also like the Weaver Air Flex. Maybe the combination of the two will give me what I am looking for. If only the Air Flex had the Smart Cinch technology, life would be good!!
