Bush league i think. I like those people who buy a good calf at a sale and leave the sale lot number ear tag in like its gonna help them in the ring. Oh, you spent how much money on lot 8 and haven't even cracked the premium slot once. LOL
I don't like holes in my show calves ears, i don't mind tagging them as they move to a production role though.
Hell i dont even like the TB clip, i just get the tattoo on the calves.
