[3.5] Alternate Combat Rules

[Coplantor]

I want to hear about them. Anyone here uses a different combat system?
Homebrews perhaps? I'm running a low magic campaign right now, and I want combat to be more... versatile and dynamic. I'm reading 2nd ed COmbat and Tactics, and dividing the combat round into Very Fast, Fast, Average, Slow and Very Slow phases might turn out... intresting.

But what about the playground? Do you guys have your own rules to make combat more cinematic or do you use the standard rules?
