Peter,
We use lodgepole for most of the workshops at Pingree Park. It doesn't have problems other than twist; it's notorious for it. All the storms on the Front Range, i guess, result in spiral grain. It can be severe. So put a spec on your order of the most slope of grain you will tolerate; I think #2 has a 1 in 10 maximum.
E-mail Peter Haney (haneyrmw@frii.com) if you want his take on it; he orders it for the workshop.
