I have yet to come across a suitably packaged SMT tantalum cap to replace the aluminium electrolytic SMT caps. That's why I always use through-hole bead type tantalums in these situations. They are easy to solder and easy to visually inspect. If you equalise the forces they don't put any excess stress on the pads either (unless you're really clumsy with them). They are a bit more expensive but for the small numbers needed it doesn't make much of a difference (and compared to the amount of money spent on old Mac stuff it's pretty irrelevant ).
