Tax is NOT the place to be, IMO. Most tax attorneys I know that still have jobs are incredibly slow (almost as slow as corporate attorneys), and I know quite a few that have
been laid off
"left their firms as a result of natural attrition or as a result of the normal annual review process."
Bankruptcy is the key, but I wouldn't necessarily switch over to bankruptcy unless you actually had a passion for it.
IP has been doing generally well, but as recent posts at ATL have shown, even some of the premier IP firms have been effected.
