*nods* It seems like what a lot of Furies do is swap out Spirit of the Bat for either Verve/Vim or Hunt depending on the needs of the group. If the group needs extra hitpoints or you are in "travel" mode, then Hunt for sure. If you are in a long fight, then Verve/Vim instead of Hunt is usually the best choice to give you some extra power to work with. Bat is pretty much always up regardless for me these days. The extra in combat regen(while small) is too valuable to sacrafice.
