Seems this thread has been brought back from the dead, but it's a good one.
A comment on tail number, I realize ADSB doesn't work in all areas, but I find that the abbreviated tail number helps me to pick up someone on my tablet if coverage is good. If my plane was a unique color I'd use color, but otherwise 90% of cessnas are white so it's useless. I find that the extra couple fractions of a second can help there.
For me, XC it's: "Skylane 38U, Big Creek for Chamberlain, nine thousand five hundred."
If I'm entering the pattern at a strip, it's "Indian Creek Traffic, Skylane 38U downstream for upstream landing, Indian.
Non-airport reporting points can be confusing for new pilots. The extra couple of fractions of a second to read out altitude per FAA guidelines is superior IMO. Again, because of the shear number of noobs out there, including myself, who may not understand the lingo.
