Matt,
I also find fully stabilized woods brittle and limit my use of it too. I will use it on pieces that dont require the peining of pins. It has very little forgiveness, but it works great for integrals and drilled blocks. Let's just say, I'm careful about when to use it. Some of the stabilized woods I see at the shows have a lot of natural occlusions. I wont touch these. Karl has the right idea by choosing his wood and having it stabilized.
I like having the option, but frankly, I like the look of the heavy, dense woods that are naturally stable. Lin
