Ooh, lots of ideas! I'll keep working on these until I get bored. :)

Hope everyone else sees the gifs the way they look when I view them wth Animation Shop instead of through the browser.

LOL Valandar. At least, I hope that was a joke...

Here's two gallops for the Charger, rotary and transverse. I'll swap the leads for them as well. I'll have a go at Walk Designer and Charger versions of what I've done already, and then maybe get on to some of the other suggestions. Some of them won't really work with the basic Poser horse, though. The prancy walk above is about as prancy as it's possible to get without it looking deformed. :(
