Ross,
I don't think the west window will be sufficient unless your winters are predominately sunny. My winters are often over cast for weeks, not dependable enough to grow anything, maybe an ivy. Your figs will be weak and lanky, in that case I say wait until spring.
I use T5 HOs, pretty economical to run 16 hours on, 8 off. Something to consider, you will need more space, more light as they grow. About 60 cuttings can be placed under a 4 foot light (6 bulb), but 60 plants growing in quart size will take up double that in my experience.
But like others said above, gives you time to nuture, and get to know each one before busy spring.
