Tim, you mean like this ???

This guy didn't chuckle, when at the landing they pointed at this log in a pile with others like it, at what he saw as a pile of slash...
He literally refused to truck it the first time, I believe he was quoted as saying - " Therah is simply, no way possible, therah, is any carpentah, anywerah, crazy enough to want that useless pile, 'a blankin bug food"
Natty curves are a whole different level on the matrix of timber supply. Once foresters and loggers learn mills want something longer than standard lengths, they're happy to supply them - The out of the norm, unstackable, slightly outside the market (touched timberframer) aspect of dealing with crooks and curves, sometimes makes them see dollar signs - and that, from the chipper bound slash pile (Think of the beautiful curves spit into the air every day) that really aren't there.
The trick I think, is to make it as easy as possible on their end. Have them just put candidates aside to then inspect and purchase, and maybe even arrange trucking yourself, so the time spent unloading your "wierd load" doesn't knaw at the back of their heads with how much more they could be making if that knuckle boom were swinging real logs at a real mill.
Like long stuff, it is in part, about that end of the market understanding that this end is here and in numbers where the market can no longer be called "niche".
