Great feedback, Gang. Thanks.
To answer Ir64's question, "What would you like it to do better?", I was looking for an inexpensive way to do lots of ground testing. Having used the CTLI (Christmas tree light ignitor) many times on the ground I became more and more confident in using them for live flights.
First step: use CTLIs for low altitude (< 1000') apogee deployment with a motor charge backup. Low altitude flights make it easy to spot redundant charges at apogee. Good results.
Next step: Dual deploy with CTLIs using oversized drogue at apogee in case of main charge ignition failure. Good results.
Over time the goal changed from having a cheap deployment charge to having the most reliable solution possible. E-match still takes the crown. But CTLIs have been very reliable. Crazy as it sounds, most often the tungsten filament is still intact and continuity is still good post launch.
