So if one is good does that mean two, three, or four, ladies at the same time are better? Curious to hear some thoughts.

One is great, but two is better. Two girls in a total coverage sinking/resurface scene is great.

Nothing wrong with seeing two ladies going down.

I prefer one. Feels more intimate.

I think it depends on what you're looking for in a scene.

Solo girl scenes are usually more intimate, just the model and the camera, but multi-girl scenes can be more playful, taking turns to push each other over into the mud for example.

We've done some of each, for example here's Veronica solo in the mud:

Here's Maria and Rosemary having fun wrecking pristine white jeans in mud:

And here's Friday and Chastity deliberately pushing each other in:

It really depends on what they are doing and what you are going for. I'm a fan of multigirl stuff. I love the playful interactions (and even not so playful but still scripted humiliation and such). Not a fan of actual mean girls, but when they are playing a role I can dig it.
I would suggest though to ALWAYS have some kind of facial coverage though. Way too many of us facial fans out there to skip that and honestly, MPV is HORRIBLE about letting faces get away clean sometimes or just flat out not showing the "after" footage once they have submerged (even including it after the credits should be fine). I for one could care less about quicksand but when two or more girls are involved, I'm hoping for facial coverage.

I have to agree with it depending on what you want at the time. More is not always better. For instance, six women playing mud volleyball isn't has hot to me as one of your scenes with Kym just going to town in a mudpit.

But at the same time variety is the spice of life, and I've really enjoyed some of the multi-model movies in the past that were more playful.

Then ultimately, most would agree that none of these compare to a personal experience.

I'd just keep doing what you're doing.

For my tastes, three women together is the perfect, magic number.
Implies playfulness, excitement, sexuality, exploration, and letting go

Of course the more girls the better

But I do like scenes with one girl, however, my favorite is when 2 girls go at it mud wrestling.. starting casual, to various level of nakedness .. oh.. and not to mention it's even better if its happening unplanned

It depends on the activity. My messy preference is female wrestling so anytime there's been more than two females at a time 99% of the time its turned into a clusterfuck. The exception is if there is a 2 on 2 tag match and the producer or ref can keep it one on one or at least the interference to a minimum until the inevitable free for all climax.

That's exactly what that means. Also, multi-girls aren't just for mud anymore.

As a one-man band producer, one girl or two girls max; any more and I don't know where to point the camcorder. If I moved to two camcorders, it'd be one on general view and one on close-ups, so still two girls maximum.
I tend to feel that way too when watching other producers' stuff.

Hell yeah!!!! I would even go so far as to say 'better' scales exponentially - at least through the low to mid single digit integers. I suppose once you hit 10, 20, 30 girls, then there is some sort of a plateau and it just becomes a muddy crowd. But 3, 4, 5, 6... seems to be the sweet spot!

I like a single girl sinking, helpless and no one to save her. Just my personal preference.

I +1000000000 this. It depends on whats happening. Using Potato's example, one girl just going to town in the mud is better than six just playing mud volleyball. However, multiple girls going to town in the mud and having a fun, cheeky, playful blast (or sexy times depending on their feelings) is much more appealing than a single girl about half the time.

When you know the girls are really having genuine fun with the mud and each other adds to the appeal.
