Well put Tamara.
I have been accused of being a "dive snob", but I figure it was cluelessness or bravado. Very few cave / advanced diving buddies, they are developed, not invented. Will dive with _almost_ anyone simple OW, easy caverns with less, then narrow it down as logistics progress. There are some who I’d jump in with a lot quicker, basically if they are same agency / group / discipline. Being totally on the same page is critical for anything that reaches my personal limits.
