RE: Any pointers on my first trad hunt?
I know the summit has a reputation as a real tree grabber, but if you'll be doing any leaning out away from or into it, you might consider getting a couple ratchet straps and really cinching both parts of the stand to the tree just for an added measure of safety.
That and a good safety harness hook up, and you should be able to find a position you can make work.
