Does anyone know what the difference is between the new (msd) Hyfire 690 and the old Mallory 690 with the side terminals? The new ones are cheap enough for me to experiment with, but I have a line on a nib old style one that looks nicer. The new one seems to have more connections. The old one doesn't seem to have a battery+ connection, and I'm wondering how that will effect points life as I intend to use them as a trigger. Sent from my LG-H931 using Tapatalk
