  The location of the (gamma,p)/(gamma,n) and (gamma,alpha)/(gamma,n) line at
gamma-process temperatures is discussed, using updated reaction rates based on
global Hauser-Feshbach calculations. The results can directly be compared to
classic gamma-process discussions. The nuclei exhibiting the largest
sensitivity to uncertainties in nuclear structure and reaction parameters are
specified and suggestions for experiments are made. Additionally, the impact of
employing two recent global alpha+nucleus potentials is discussed. It is found
that branchings at higher mass depend more sensitively on these potentials. The
case of 146Sm/144Sm production is addressed separately. Also in this case, the
more recent alpha+nucleus potentials seem to improve the issues concerning the
production of these Sm isotopes in massive stars. In conclusion it is found
that it is unlikely that the calculated underproduction of p nuclides in the
Mo-Ru region is due to nuclear physics deficiencies but that problems at higher
mass number may still be cured by improved nuclear input.
