After talking it over with Andy at My Reef Creations, I'm going with the MR-4R. He also recommended the BL55 or BL70. Not exactly sure if I'll go with the Bluelines or some other pump, but I'm doing more research on that. Since the MR-4R is 32.5" it should fit in the stand nicely, so noise should be reduced compared to sitting it outside the stand.
Thanks for all the opinions and recommendations, appreciate it ! If someone has some good real-world experience with the pumps that would work well for this skimmer, chime in.
