MTR...as you can see by the FAQ's posted earlier by me, the ASA used that term as well on these questions. I'm not saying it is the correct term for use but you have to give a little leeway in your exacting standards of terminology if the sanctioning body has posted that term. Most of us know that it means the bat is no longer on the ASA approved list of bats allowed to be used in that sanctioning bodies tournaments. As for the term "grandfathered," again, most of us know the term as being meant, 'until proven otherwise, it is still sanctioned for use under the current rules.' I do understand that terminology of the rules are pretty exacting, but please, give the general population a little slack in slinging lingo around that many others use in day to day incorrect utilization. Especially in this instance
