Sorry to hear that Brooklyn changed her tune
Our businesses are quite different. Because I was simply making muscle/lift vids, I never had to find girls willing to do nudity and/or more risque types of adult modeling. I sought the young, college-age girls because they are fit, and usually stronger than the 30-plus age group (also more willing to push themselves to prove their strength than older gals). I got models for davemeister and collegemusclemag through university newspaper ads, word of mouth, craigslist, modelmayhem, omp, etc. One of my favourite shoots which I would love for you to "borrow/imitate" with your models was my "New Lifter Sisters" video. It featured two college-age sisters, both in the 125-130 pound range, lifting me effortlessly...passing me back and forth in cradle carries, doing super long bearhugs, piggybacks, etc. The girls had so much fun and liked to show off.
That's the thing: adult models who are just being introduced to lift and carry will likely not get it, and will go through the motions, but not be very convincing. Of all your models, you can really see the difference from a Moxxie, vs. say, a Cambrey Sage...Moxxie seems to enjoy it (or at least looks convincing), whereas Cambrey seems to be "faking it."
Again, they're two different markets...I would never have been able to shoot my models with the sexual elements found in your videos...that's why I'm so high on JC Simpson...she has the look of the slim, athletic girl next door, but is also willing to do more intriguing/risque stuff combined with lift and carry. That's why you do so well...people love that you produce lift and carry alongside the other stuff which enhances the whole thing.
Sorry for rambling...I'm bored today and have been spending way too long online

p.s. in terms of other adult stars that are desirable for lift shoots (and to show those beautiful biceps off), add Cheyenne Jewel, Ariel X, Wenona, Dia Zerva, Julie Squeeze to the list...I don't really get why those girls have done so much wrestling stuff but only minimal lift and carry. I know if I was still producing stuff and they were accessible, I would totally work with them.
