According to Kevin from OwnHammer, all of those are considered "V3". Except for the 212 MAR-66, Kevin said this about it: "This was a transitional library between V3 and V4, leaning more the side of V4."Just realised I have a whole bunch of V3 IRs from Ownhammer that I forgot I'd bought, and the few I sampled sound pretty killer. Maybe I don't need V4 after all? Pretty sure all these are V3 except the bottom two right?

I also feel that this will demonstrate the value of the Player Packs even more, and make things much clearer to define in terms of the line in the sand between them and the OH site contents to where it will be easier to fall to one side or the other.
