The first few staves I dragged home were so twisted that it made me a little gun shy and from then on I've always wanted to see what the grain is doing. On some woods, like yew, you can't tell whats going on inside. Most of the time you would be OK to saw but be prepared to be bitten. I've found that steaming the twist out is not a big deal. Although I'm not sure if it will last, I've only been at this for a couple of years.
