I think you need to know what's a deal breaker for you - not in what you would settle for, as you should never settle - but in terms of how much you'll love the piece. For instance, I too have a strong hardware preference (for PHW) and have turned down many GHW bags, but I accepted my Kelly 25 in Barenia with GHW because I knew in a K25 the hardware is small and also it differentiated the bag even more from my Gold K28.
Now, if I had thought I'd look at the bag every day and wish it were PHW, I would not have bought it.
I turned down a dreamy Raisin K32 for being GHW because I know it would have bothered me, even slightly.
The other option is to take what is offered til the HG shows up, but you will then eventually be left with bags you either have to rehome at a big loss, or, if your funds are unlimited, bags you simply don't wear.
