Barr hogs!?!

Since I was a kid I've cut and released (My uncles did 99% of the cutting) well over 100 boars and have caught 5 in all that time. Here in hawaii the mark is just a notch in their ear so there really is no telling which is yours. Majority of the pigs we catch are loners unless it's a momma and her babies. I've noticed the barrs like to sit and fight more but have had a few smart ones take off. I've heard a few reasons why guys cut off tails and ears from marking um after being cut to making it harder for the next guy to catch which in turn lets the pig get even bigger. I don't do it. I've wondered what % of them make it on a few occasions. I've recently started using numbered ear tags that also have my name printed on them and then I write in the date caught but have yet to recatch one yet or hear of someone else talking about the tag.
