The purpose of this post is a place-holder for anyone else wanting a flashy 9mm load.
I set out to load a 9mm round with a lot of flash using Blue Dot and Berry's 115gr RNDS plated bullets. I started with Alliant's max load data, backed it off 20% (8.6gr @ 1.130" for a 115gr GDHP is their max) and made 10 sets of 5 rounds, ranging from 6.8 gr to 8.1gr
The load with the most flash was found to be 7.7 grains of Blue Dot at 1.135". The video description explains the last 5 rounds are this load. Running it all the way out to 8.1gr obviously increased the recoil, but seemed to diminish the flash. I assume the pressure was beginning to increase, and causing a more efficient burn.
http://www.youtube.com/watch?v=FDBduQSqn84 - 7.7gr was found to be the best load, and the one I will move forward with. It is the last 5 shots in the string.
I don't believe I am seeing pressure signs. These are the cases I recovered:
Sets 1-5. The sets are ordered in rows, with 6.8 being at the very top, 7.0 being below it. For ref, (6.8, 7.0, 7.2, 7.4, 7.6)gr

Sets 6-10. The sets are ordered in rows, with 7.7gr having two recovered cases, and 7.8gr just below that. For ref, (7.7, 7.8, 7.9, 8.0, 8.1)gr
