Hi guys, I'm about to buy an Alta but I have a few questions. I can't really decide between a M10 or M15 configuration. I'll be primarily flying a GH4 and every now and then client's RED Dragon. The thing is I'm in Bogota Colombia, (8600') and I know Im very limited here. I don't always film here, but the show I'm on right now (Narcos) is mostly shot here and around. I know the density altitude will prevent us from flying a RED and have us sticking to the GH4. What is the configuration of choice here ? M10 or M15 ? It's a tough choice.
