Randonee Boots in Alpine Bindings?

Yesterday I used my Spatulas for the first time at Crystal(great fun, point them and hang on and  try and keep even pressure on both feet)

I have Garmont Adreneline boots and was going to change the sole to the DIN sole but I had powder fever and didn't want to spend the time so I clicked in with the backcountry sole still on to try it out. It worked so off I went.

I suspect that using the backcountry sole in alpine binding has a detremental effect on the releasabilty of the toe piece and would welcome some advise.
Changing the sole involves about 11 screws in each boot but it's still a pain.
I had no pre-release issues. The binding is a Tyrolia, Cyber  Carbon D9.
Can any of you technical types comment on how much this comprimises the releasabilty?
Thanks.

there's an excellent thread on the TGR forums about this topic

Thanks Pete A. I read the thread and it was very useful. Thanks for the link.I need to remember to search TGR before asking questions first as it appears there's not a subject on skiing that hasn't been talked about on TGR.
