In this day and age I would not consider a Punchaz if you are planning
on acro. Look at the load limit/flight envelope chart and you will
see that it has a very low VNE and the limits to negative Gs gets
smaller as one approaches VNE. Any lack of attention in a blown
manuver and WATCH OUT. There is also quite a history of people not
recovering from spins. I participated in assembly of a Punchaz and it
was not pretty.
