Thats a fussy customer, I'm doing wood right now as well. It all burns. I'm currently doing some pine for kindling and mixing in, and I'll use the entire tree, sawdust and branches to the ends, then back to hardwood. Neighbor lost a 80'-0" or so pine, nice healthy tree, with a double trunk part way up, 42 years old.
We had some blow down from a recent storm, left me some nice leaners, barber chairs etc., up top in the 11 acre woodlot of older hardwoods, definitely time to do some more logging, just wish the ground would freeze, got soft with a foot of snow just melted off, my guess is it will freeze. I kind of like working outdoors this time of year when the temperatures are tolerable, mid 20's-30's, no bugs, no high heat-humidity, and frozen ground. If the weather holds, its possible I'll get caught up on all the recently dead elm, storm damage and so on.
