There are many types, I'm not sure which it was I had but we do seem to have a fair bit of goat willow and m around here. I'm not sure what the bouncy characteristic is called, but it is a measured thing and there very reason for Willow's use in bats.
What are baseball bats made from? Hickory isn't it? Makes me wonder if willow would make a good axe handle, never heard of it being used though.
Anyway, I like to try most woods and learn, but now avoid willow, hard to split and dries to nothing much.
