A new company that is perhaps commited to support and enhance a single new figure for the foreseeable future, versus in the business of creating figure after figure, upgrade after upgrade, that are not all compatible?

Usable versions in Poser and DS, make it easier for content providers to make things for both programs, if you switch between both, like I do?

Widest 3rd party embrace and support of a new figure for Poser that I've seen in a while is exciting to see what is coming (which again, makes it easy to make a "ds" version, and may as a result bring more content providers back to doing so, that were lost in the genesis release era).

These may be some reasons to do so...

BTW, you can auto-fit, you just need a clone.  See tutorial on my site.
