I'm pretty sure my 9" Geryi is the largest in the U.S. along with hareballs. I don't know of any bigger. Previously, PIRANHNUT had a 11-12 incher wich Amazonman bought and had for one day before it died.
As far as I know my 8.5" brandtii is second only to BDKings.
Wayne Mah has the largest Manuelli, Knifeman had the biggest tern... 14 inches, dont know who he sold it too. Chud had an 18 inch rohm. Im pretty sure that my brandtii that used to be hareballs is the largest in the US. The largest caribas are up near 14+.
