It checks badly, takes forever to dry and takes some set. The bendy handle may be the way around the checking. If you cut OS to the pith and take reasonable precautions(seal the ends and such) it doesn't check much at all, at least in a humid climate like I have. In the past I have tried to keep the handle full size but it almost always splits. Bendies got no handle, so no split. You just have to bite the bullet and wait for it to dry. It seems to hold a little moisture until you start to work on it and then it will bite you, as checking or set. Once it's dry heat treating seems to take care of the set. OS loves heat treating even though it's very dense. I'm thinking the heat drives out that last bit of moisture. The stuff I'm working on right now was cut in fall 2014. It's been in my garage(unheated, runs about 60-70% RH) for 3 years. I just put it in my warm box at a steady 50%RH and I'd bet it will start loosing weight by tomorrow.
It's very tension and compression strong. If it's going to fail it will pop a splinter at a pin in the top of the crown. I'm fortunate to live in walking distance of a lot of OS, up to 2-2 1/2" in dia. Having lots of large pieces give me the luxury of being able to pick and chose. If you can find a piece with no pins on the top of the crown in the working section of the limb it's almost break proof.
I think I can make the tips even thinner. I started this bow with pin nocks. After picking up the string for the umpteenth time I tapered the tips down to the pin size and glued on some overlays. I was quite surprised when I measured then and they were 1/4" wide. OS is extremely strong so I think I could go to 3/16" or less. I would start to worry about the size of the glue joint then.
