If your captain supports and likes spin, my first captain was an offie, a bloke called Neil Samwell, he was a legend, brilliant bloke and gave us spinners all a good go - it makes a big difference.
I'm pretty lucky, I've been in the nets against a friend who played under-19's state cricket with Ben Hilfenhaus, he's incredibly knowledgable about the game but naturally not being a leg spinner, there's only so much info he can give me. He'll be my captain next year as we're going to start a whole new team, I've got a group of 13 mates and we're gonna enter ourselves in 4th division cricket, just to see how we go He's a massive advocate for spinners though, he, himself doesn't bowl though.
I will purchase the book next payday for my kindle, thanks heaps again Dave!
