Matt and I acquired the CMRR MEGA PRESS sequence back in 2016, but we never got around to testing parameters. I had a couple of conversations with Eric Porges at UF a few years ago and I vaguely remember him saying they had a preferred sequence. If we do proceed with MEGA-PRESS, I'll want us to reach out to him first.
