Sorry, I'm givin' the nod to bold slugs, as well.  I resisted their call for awhile - but dammit, they look good. And make the read FAR easier....

I find them very distracting.  "Look at me!  Look at meeeeee!"  I don't want to look at you, mini-slug; I'm halfway down the page trying to read dialogue.

I use bold slugs and I'll never go back. They make scenes MUCH easier to identify and they look good...and more modern...

Have to agree Pia.

I have been doing this for a loooooong time and find it really easy to follow when I'm reading a screenplay.

I'm not changing for anyone !!!!!

If you're giong to use bold Slugs, please...please, write good, solid Slugs, because if you don't, and you bold them, they are going to stand out and it will be extremely obvious that you don't know how to write good, solid Slugs.

...and...you know who you are, piss poor Slug writers!  

Yeah they seemed to be getting more popular these days. I don't do it myself but I see why they are becoming favorable, I've no problem with them.

I think Jeff makes a good point though, since they are in bold and stand out, it's even more important to ensure they are written properly.

Writing for myself, the bold slug lines help you flip through the script.
If I see too many or too few, there may be some scene issues worth looking into.
Anyone flipping pages should see around 30+ bold scene slugs for a three act story.

Also, I think format should be adjusted depending on what you're writing.
For instance, I'm currently writing a high tech action/thriller.
There's scenes where the modern science flies as much as the bullets.

Strong and clear -Bold & Underlined- slugs stand out from the action/tech heavy prose.
Without them, those kinds of scenes would look like a MARATHON to read through.
Which is the last thing I want when I'm spinning a set piece to entertain the reader.

Bottom Line:
I'll use any slug format that helps my spec stay out of a prodco's trash barrel.
They can be used to make a read more appealing, depending on the story.

If you've got a script with long meditative scenes, I wouldn't bold a thing.
Since there's a lot of white on the page already, keep it simple.

Cheers,
E.D.

I don't need to flip pages as I read my scripts over and over again until I get sick of them. I know every scene and instinctively know if a scene is too long, because they generally go over 5 pages.

Personally, I don't care about bold slugs. If someone paying a lot of money asked me to do it, then I'd do it. I'd probably ask why, but if they're paying, whatever. Otherwise, I do whatever I want... in fact, now everyone else is doing it I'm even less likely to do so.

How would bold slugs make action-heavy prose seem like any less of a marathon to get through? Twaddle is a good word for that.

To add,  Celtx,  when in edit mode,  has its slugs in a nice grayish highlight which I think looks sharp. Easy on the eye.
