Smallest deck isn't necessarily the best option IMO. The smallest total RIG size is what I want.
2 options (1st option is considering you appear to run the HO's):
1. HO's > Naiant IPA > Deck of choice (M10, etc). The IPA is metal, but you can probably put it in you "stuff" with your phone when passing through security.
2. DPA d-vice w/DPA 406x's. Not available yet, but if you can't get those mics & the d-vice (preamp/a>d>usb) into any venue, you ain't getting anything in. Hell you don't even need a recorder...just your phone. This will likely be my next
rig.
