I'm kinda similar here, except I wrap my LX (the choice for still using LX straps is that they are strong, long, thin and black without large logos or writing on them) shoulder straps around my right hand and hold camera by the grip with right fingers.
I'm a manual focus man, left hand is for additional lens support and focusing
. I find this a comfortable and secure for long periods of use and it's also quick when switching bodies.
It means I can carry the camera low (at end of arm) which can be surprisingly "stealthy" when required even with biggish fast glass.
