[CentOS] raid boot partition size?

Hi y'all
I can't tell you which msg thread it was in but after an install and the
system hangs...one of the responses was that the boot partition might be
too large...

Although most of the installs (raid 1) I don't have that problems but I
have before. I usually make my boot partition 200mb.

my question:
What size do y'all recomend for the boot partition, 100mb?

thx
