In my experience, Tim does test the bats and I trust his judgement - the guy has more years in the industry than most. I have a few "pro" bats and some have superb grains, whereas one or two are not as pretty but respond incredibly to both mallet and ball! I would simply view them as excellent performance bats - not worth too much overthinking about which sponsored player or where they were heading for. But if Tim has rated them as that quality, then they will be quality!
Hi My friend was considering this https://www.ebay.co.uk/itm/387624873598I know grains are not everything but is likely to be a pro bat or too hard to tell ? Not cheap either , is it slightly used and refurbed ?
