Completely agree, you get a lot of details, like folding etc simply because it is dynamic. Which you can get in conforming as well, the biggest problem though with conforming cloth is that no matter how well it is made, its impossible for the vendor to make it work for every single situation, meaning if the character is sitting down, you would expect a lot of folds around the hip area. But unless that is build into the cloth is self, it just wont look correct.. And as you say, to have the cloth interact with other objects like a floor is very cool.

But besides these things, I think the main reasons why I like dynamic cloth, is due to mainly 3 things.

1. Speed

I started using conforming cloth and for some items these are really good, like armors etc. But I always found that working with actual cloth and them being conforming is very slow and annoying actually. Obviously is very fast to just click conform to.. select the character and apply a pose and its done. But the amount of clean up you have to do in forms of endless amount of dials you twist and turn to fix it for a given pose and then in the end you still have to accept that it doesn't really look the way you wanted were taking a lot longer compared to simply using dynamic cloth even if you have to simulate it and in the end you get a much better result.

2. Morph independent

I think this is one of the biggest benefits, which is that you don't really have to rely on morphs that are in the cloth. You can just change the character and the cloth will automatically react to it, as you say you can move the character to give the effect of wind, air resistances etc. And even with the copy morphs functionality it will only get you so far, it will not solve the "static" look . And still wont solve the issues pointed out in the above. To me it give a lot of freedom to work, so the character is what is important and not whether a given cloth item will work with what you are trying to do or not.

3. Randomness

That you never really know what you get is something that I like a lot about dynamic cloth, it makes it fun to work with, seeing how the cloth behave for varies poses.

Regarding the wind there is actually a wind force in Poser. This image uses it.

As you can see the wind presses the dress backwards, which would be near impossible to do with conforming cloth. Im pretty sure its in Poser 9 as well? Have you checked the Create menu at the top... I think its called Wind force?

I personally think that 0.500 of depth and offset is a bit to high. But again it depends on the cloth so there is not really any wrong setting as such. But I usually work in the range of 0.200 to 0.350 by default.

Shrinking a character before simulating is a good way to make a tight fit, have used that trick as well. And I don't really see any other solution to this currently as the cloth room doesn't have a shrink functionality. But would like if it were added at some point, as it would really expand on the possibilities for dynamics.

Im not really sure what you mean with changing the size of the cloth from 100% to 98% after simulating, because I would expect that to cause all sorts of poke through problems, but maybe I misunderstood you?

The last thing we need now is decent dynamic hair, that would really make things interesting, but guess that is a whole new topic :D
