surely before u say a bat is to heavy? u should use the bat 1st?
if you hadn't weighted it would u have noticed? i think its a shame for people to get rid of an amazing bat just because its 2oz to heavy?
I make a point of never weiging my bats when I get new ones.
Ask for a weight, use is, if it feels way too heavy or light then I might lob it on the scales, but I think it just messes with your head if you weight it first up. Especially given your scales could well be off. I'd hope that most batmakers have decent scales and are honest about it

I'd also add that this isn't having a go at anyone who's ever sent back an overweight bat, but it does amaze me when people send it back without having a hit with it first, albeit maybe after confirming this is ok with the maker
