One thing to consider here is that the shoe-mounted meter doesn't connect to the shutter speed dial, as do the ones made for Leica-M and old pre-Spotmatic Pentaxes. So the settings will need to be transferred manually from the meter to the camera. With the Gossen DigiSix and DigiFlash, there's an additional step of transferring the EV meter readout to the meter's calculator dial to come up with shutter/aperturer settings. Don't know about the Pilot2.
I'd think it's more convenient to use a regular hand-held meter. It's generally not necessary to meter each and every shot if you wave the meter about to get a sense of what the surrounding scene will require.
I usually use the meter's incident-reading mode to eliminate differences over object reflectivity in the scene. Setting the camera for the amount of light falling on the subject means predominantly light or dark subjects will both be rendered properly. Reflective meters can be fooled by this, so the user needs to be aware of it and compensate.
I'll just loop the lanyard cord through a belt loop or around my neck and slide the meter into a pocket. This is where are large meter like the great Gossen Luna analog models can be just too big. I really like my older Gossen Super Pilot, and slim newer Luna Star F digital meter.
