Final Draft... "Tight"

I am one of those simple folk who use their computer like a glorified typewriter and that's about it, never really exploring the bells and whistles...

After writing several scripts I have only just today...

discovered under "page layout" (on Final Draft 6) that you can change "normal" to "tight" or "very tight" and cut out 7-15 pages in the process...

So my question: can you get away with this?? I think TIGHT looks pretty similar to NORMAL... or is that just a no no and easily caught by an experienced eye??

Any tips to trim a bit of fat on FD would be welcome?


thanks
