Had some bats from reputable bat makers with slightly wonky shoulders, I guess it's the nature of something that's handmade. Funnily enough, all the ones I've had which have slightly wonky shoulders have always been absolute belters. (From personal experience, my TK pro bats tend to have slightly wonkier shoulders) I think I've even had a couple of Lavers that have had ever so slight out of sync shoulders!
This one looks a gem, seems like a little more wood to the toe and a slightly lower spine makes the shape look a bit more productive to balls hit lower down the blade. How does it tap up? The only thing that would have me worried is the weight, if it says 2.11 but weighs 2.12 and a bit, they probably weighed it ungripped!
