RE: TV Hunting show hosts and their credibility....
It is quite possible that their opinions change from time to time. I know mine do.
It is also possible that with so many quality products available for hunters that all of the products they push are of high quality.
Honestly, I have only switched one product I use in the last 7 years and that is I bought some Rage broadheads based on reports from GMMAT, Beagle, and TXhoghunter. Not based on any pros.
