Totally surprising post, and even tougher to comment on, but very exciting one
As these pics show, amount of butterfly stain is varying on every single bat, which makes it even more difficult to assess their quality.
Butterfly stained bat with no bar in the face or on the back will play the best, even if it is colour only stain.
These bats will sound hard.
Butterfly bars don't add/deteriorate bat performance, only esthetic, they add hardness if not pressed correctly especially near to splice.
Mostly their grain structure will be as good as, at least, grade 2 willow, they do feel bigger for their weights.
Why not asking a high price if they would perform as grade 1.
For me this stain is purely cosmetic but it takes longer to find the right one
