Haha, just when you think you have thought of it all.

Sounds like you have done your homework and have a good spot. I noticed you mentioned you will be hunting it in the morning. That is probably your best bet, as with the warming sun the thermals will rise. If you would hunt it in the evening there is a good chance as the thermals lower your scent would travel down as onto the trail below. Good luck and I hope you bag a bruiser there this year.
