Dave - seems a lot of people, myself included, would prefer thematic sets rather than model exclusive sets. I would, for instance, purchase a set of three movies with a JMI or cylinder measuring theme, rather than a single model doing one of these acts with two other scenes I'm not as into. The downside I know from your end is that you'd have to have at least three model shoots before a set could go online. A delay in revenue, but maybe more profitable in the long run?
At any rate, I do want to let you know that you still produce the highest quality videos in a field dominated by hard core watersports, which I believe most of us are not into. I really hope everything works out.
