Honestly, even though it might end up similar to the summer camp, I think I would like the cheerleader story the most, maybe even because I guess it would end up as another very long story. A group of girls who are knowing each other, probably a bunch of good friends among them, that could lead to some very interesting scenes with multiple girls. Also, right now I think at least three of those girls could have made it into my top 10 if they were in the summer camp.
The woodburn story would also be great to see, I like the girls and I like most of the story. There are some scenes that would be amazing to see, but also some details I could do without, and especially towards the end I expect you would have to change a few things.
The sodom story seems interesting too, very intriguing with the ritualistic setting, and I like to see the girl already gagged and blindfolded.
The other three previews don't make me that excited for the potential stories yet - the torture devices in the last one are looking great, the picture is the most exciting one, but you could still use them in a different story.
