motor certification - meeting DoT requirements vs. publishing

its fair share of times and I remember reading the questions, but can't

What does everybody recommend for igniting the second stage of a HPR?  I
recently purchased a PML Thunder and Lighting and see that they have their
system  but is that the best or is their a better system.
Thanks,

I am looking to gather hard data to be used in identifying the most
common failure modes of sport rocket flights.
I am wondering if any clubs or sections might maintain flight card
records which include flight results and whether they might be willing

I am thinking about getting an Aztek 320 airbrush.  I've heard some
