Mine arrived today (well, the second half).
So far I like it. It definitely feels truer in shape to the Butterfly than the last Butterfly AL, and doesn’t feel anywhere near as chonky. The last Butterfly AL has a very distinctive thud when it hits the end of the string, but this one has none of that. That said, it’s still a little heavy for my taste in responsive play. I like where the response is. It feels very authentic to a single wrapped Butterfly.
