Well, low perigee has some definite risks attached.  The high 
velocity at and near perigee that near the atmosphere (and near LEO 
as well) is definitely a factor.

Also, because we're still pretty close to GTO, there might be some 
orbit crossing debris (like booster upper stages and spent PAM's) to 
watch out for.  The final orbit was supposed to be a lot more in the 
clear.
