I'd go 3:1 with small pulley on stepper.

If you want to relieve some stress on the motor then use some form of counter balance, either weights or gas struts.

I have pulleys for 3:1 on my Z-axis as well!

However, this interesting response was a reply when I asked the very same question: http://www.mycncuk.com/forums/faqs-p...html#post47446

Thanks Birchy.

I had already decided on a key way driven pulley on the Z axis Leadscrew, has the existing shaft has one in, so i will utilise the existing keyway.
