Sound like a perfect situation for the epoxy fill. I think maybe Del has some PTG Journal articles describing a technique - maybe someone else - maybe check the archives.With epoxy you can get all the way under the bridge also (squoosh/moosh application technique). I haven't tried it, but the process involves taping one side of crack (to act as a mold of sorts) and filling other side with thickened epoxy. Make sure the crack/epoxy is prepared for maximum adhesion (I would seriously consider the West System Two-Step Method). You can color West System epoxy to come pretty close to spruce.
