As you surmised, the same "L6" model is carried over from the V70 to the V75, Nathan...

And (in my experience) it's the model that seems to appeal most to those singers that are used to condenser mics, such as Neumann's KMS 104 and 105.

(My original set-up contained four V-70 handhelds, but I then bought an additional V-75 handheld as part of an "upgrade kit" for my eight XD-V70 systems. You can click on my pink avatar at left to see more details of my location rig.)

All of the models from the V70 do also appear in the 75, but the latter also sports additional emulations of Sennheiser's e935 and AKG's D5.

Having checked out a couple of samples from your great website, I'd only add that the few Aussie bands that I've covered in your line of work (albeit most likely in much smaller venues) seem to settle for the b58 (Shure beta58) or o5 (Audix OM5) models, with just one male lead singer preferring the mid-range "cut-through" of the 41 (Audio-Technica AE4100).
