Peerless is a good start. They have great/reliable mounts. I would suggest a flat panel mount, such as the Peerless SF660. This is a low profile mount that sticks out 1.18" away from the wall. That way it would give it close to a flush look to your wall. It also handles upto 200 lbs, so this more than plenty weight support for the 6070.
Cleveland recommended the Sanus VMPL3 for adjust-ability purposes. Well you can simply go with the VMPL2, which has a single back plate and is a much more lower profile mount.
Keep in mind the weight of your 6070 is only 112.4 lbs, in which the SF660 and VMPL2 can handle that weight support.
