Got the OG in hand pretty quick, about a 3-business day stamp approval.
Played musical cans today. Didn't quite have the lineup of cans I hoped we would...excuses, excuses..."it's my son's birthday" and "my wedding is in 4 weeks, we need to plan"

Shooter's preference (me):
1. OG
2. Nomad
3. Evo
4. A-10
5. Alaskan
The OG, Nomad and Evo could all be tied for 1st on sound alone. Really splitting hairs on those rankings. The tone thing is real though, the OG has that hollow "thunk" they've been talking about. I think it is represented a bit through the GoPro mic, not so much the iPhone. The A-10 was "crackier" to me than those three, and the Alaskan was both loud and cracky. I didn't really want to rank the OG first, but if I could only keep one it would be the OG. My offhand shooting also noticeably improved in the Rokslide 20 shot shooter drill with it.
Spotter's preference:
1. A-10
2. OG
3. Nomad
4. Evo
5. Alaskan
The microphones on the GoPro and iPhone don't capture the differences in the audio signatures well at all...but we took the footage so might as well put it together.
