Looking for comparison between Mystery Ranch Scapegoat and Kifaru 14er

[Pardner]

I thought I would check if anyone has had the opportunity to use both these bags and provide some comparisons. I have preferred the Kifaru stay and belt system over the more flexible frame and yoke system of the Mystery Ranch Dragon Slayer/3DAP line but this looks like a modified version from MR which has me curious. I am most interested in how the MR Scapegoat handled the load as compared to the 14er in your use.

Thanks in advance.
