You should be able to use something close or combine two for an average.

Don't take my word for it.
I'll usually mix and match. If I need a 30L and all I have is a10L and a 40L I'll split the difference. A little 10L and a little 40L. It's better than holding up the whole batch.

Never underestimate the potential of someone who refuses to act their age.

They are similar enough as to not be a huge difference, although an expert could probably pick up the differences, as the 20L is more caramelly sweet while the 40L is still sweet but not as candy-like.

A great way to make a good American amber is to "layer" the crystal malts for depth of flavor. Say, .75 pound of 20L and .75 pound of 80L. It doesn't taste like 1.5 pounds of 60L, though- it's got some caramel sweetness, some toffee notes, and some depth to it, while 1.5 pounds of 60L might be lacking the toffee notes and the caramel and give a different crystal malt flavor.

I would not give a though to subbing 40L for 30L, but I would think more about bigger changes in a recipe depending on what I was hoping to get in the way of flavor.
