I was under the impression they're supposed to be more durable than the average non-butterfly willow?
This comes from the fact the stain is harder and tougher wood than sap wood. Heartwood is said to be more brittle and Butterly is the opposite.
Makes no odds if you okay against cheap balls mind. To be it’s all open to opinion as they sound or feel from the stain of a Butterly gives a header or more of a dull sound. To compare it’s very similar to how a GM may sound or feel when it’s brand new but the rebound quality is still just as good.
I remember Dean from Vulcan cricket had a Butterly bat for years as his match bat and would have had thousands of runs through it, a lad at my club actually my opening partner has a all sapwood M&H which will be in its 5th season this coming one and again must have had 4000 runs from it plus nets.
What I know is that both of these bats were well looked after and used against good quality balls and were prepared before going to the crease for the first time.
By and large most on here don’t use a bat long enough. I had a horrible season with the bat last year but despite using in 7 games last summer I know mine was certainly better at game 7 than it was at game 1.
As Jonny says you just don’t get many light Butterly clefts and from my limited knowledge of making a bat so far it’s hard to get below 2.11 with the demands of a “big bat” ie 35mm plus edges and toe and shoulders around 20mm
