Screenwriting : Screenwriters trying to break in by Hunter Huiet

I use Final Draft 12

There are lots of script formatting programs available but I recommend Final Draft. It's widely used in the industry and has a proven track record. It has become the de-facto industry standard. Expect flak from many - but it's just the truth.

Honestly, if you're serious Final Draft is worth investing in for the simple fact that it's industry standard. Which means that if you ever get staffed, they're going to use FD. So you'll want to know how to use it in advance so you don't have to play catch up. It's no different than graphic design. There are plenty of alternatives to Photoshop. But most corporations are using Photoshop. So if you show up not able to use it, you'll have to learn how to use the software they've already bought, because they're not going to change to a whole new format just to accommodate your needs.

How's breaking in linked to a SW? You just find out new stuff every day... :/

Final Draft is great, and as was mentioned - it is industry standard. But if you're not quite there yet, there are lots of cheaper alternatives like celtx (which is not THAT much cheaper, but works very smoothly), or even StudioBinder. It all depends on how you like to work, what your "flow" or "groove" is. I recommend trying them out, and then seeing which aids your creativity best.

I recently switched, which was incredibly daunting, but broke through a creative barrier I'd been stuck behind for ages.

The best choice is the one that brings out the best in you as a writer. That's what will ultimately help you break in and finding the right fit makes a huge difference. All artists owe it to themselves to try all the tools available. Scrivener works best for me.
