Don't know the specific brand you've got.
I do know that everyone and his wife says willow is poop for turning.
In my very limited experience, there is a lot of truth in what they say - though at my level, free wood is free wood and that means plenty to practice on without panicking about wastage. What it did teach me was that sharp tools and good control are crucial for a good finish. (DAMHIK!!)
And it really is poop to burn, so you may as well turn it and at least have some fun.
