I've also seen a few short (ie. 50 feet high or less) guyed comercial towers
using a pointed base (although most guyed comercial towers in this size range
that I have seen have also had a flat base.) I believe the pointed base is
often referred to as a pier pin base.
I'm curious if any one has any insight into what the advantages (if any) would
be of using a pointed base for a short guyed tower.

Most BIG commercial towers are the kind that come to point at the bottom.
This design helps to reduce torque stress on a tower (I think). Most ham
towers are "flat" on the bottom.
The pointed ones use a "pin" of some sort and require guying of some
sort
from the first section. The flat ones eventually require guying at some
point.
I prefer the flat type since it is easy to temporarily remove a set of guy
wires to slide an antenna up the side of a tower. One can not do that with
the pointed type since it must be continuously guyed.
W2GD was recently injured by riding down 30 feet of tower that was
"secured"
by a pin. Accidents can and do happen on both types of tower.
