Chris,
   I've landed at Catalina twice in the past three months.  The runway is
uneven and in sore of resurfacing, but I don't consider it rough enough to
preclude you from going there.  There are no big pot holes or anything I saw
that would damage your plane.  On any given day, many planes land there
without incident, so I think you should be OK.
   What irks me about that airport is that they now collect a landing fee of
$10 per plane ($15 if you have 3 or more passengers) and I have no idea
where that money goes.  It certainly isn't being used for runway
maintenance.
