I was just going to ask about this again hoping that someone could shed some light on what nano kit would work. Or if someone changed their top cap to get the nano kit to work.
I'm not sure I know the answer to this.
I have some EHPro kits that work with a nano kit, and others that don't. All of them are KFL+ v2. One thing I do know is that even with the kits that don't work with the standard top cap, DO work when I use the Nano SS2 top cap.
