I have questions about 2 species, one which I know is good - serviceberry, and the other, mimosa, which I haven't found any definitive info as to bow worthyness on. With service berry, I am wondering just how it compares to other bowwoods, what it's particular qualities are, etc. We have plenty around here (2 species, Downy and Allenghany) so I thought it might be worth a try. The one problem I see is that you would be hard pressed to find anything over 5-6" in diameter, so it might be like working with a sapling. With Mimosa I have done bend tests (bending a medium thickness branch/trunk) to get a feel for it's qualities, and it seemed to be a mixture of soft and springy -interesting. Hope someone here has tried it.
