  Rotating IIB strings in AdS_5 x S^5 become ultra-relativistic, and hence
effectively tensionless, in the limit of large angular momentum on S^5. We have
shown previously that such tensionless strings may preserve supersymmetry. Here
we extend this result to include a class of supersymmetric tensionless strings
with arbitrary SO(6) angular momentum. We close with some general comments on
tensionless strings in AdS_5 x S^5.
