I don't care for them, never tried them. Alot of the places in Tx for hogs or exotics don't allow them. I'm worried they will either open in flight or not open properly double banded. [personal problem, i know, lol] If I were to try them, I'd go to 10 pts web site and see what they include w/ packages, you can bet if 10 pt advises them they work well.
