That's what happens when you make a stronger seat. The weakness in the
system moves to a different area. It's a great quality seat, designed
for high-level aggressive riding. Unfortunately the seat post is still
in the "basic unicycling" cagegory; made to be cheap.
Before people started jumping and hopping all the time, seat posts were
never a problem Now we're putting a lot more stress on them. Adding
longer handles to the front of the seat only makes it worse, as there is
more leverage being applied to the post.
Eventually, unicycle seats/posts will be designed around the post. It
will be some sort of a T shape, with a handle at the front and bumper at
the back, designed to take all the torque and repetition of long-term
hopping and jumping. Then, the seat can be built a lot lighter (and
hopefully simpler/cheaper), because it will only support your butt and
not be used for all that other stuff.
Your post broke from metal fatigue. Metal doesn't (usually) break from a
single hard impact. These kinds of breaks develop over the course of
hundreds, or more likely thousands, of pulls and drops. I used to tear a
lot of Miyata seat posts. My more recent ones are customized to shore
them up. They not only won't break, they help protect the seat from
breaking.
