Added a tailcap amp spreadsheet in the OP.
Right now I only have the ZeusRay and the OEM SK98 from FT. In the ideal situation (factory problems set aside), I'd have to pick the ZeusRay.
The UR18650s, the FM in this case do very well for daily driver use. All of my other cells are LCO and report around the same internal resistance from my Lii-260 (50-60mR), so I suspect the amps I recorded are at peak performance without having to move to LMN cells or doing more driver mods.
