Could anyone give a brief discription of some of the most common diffusion and gels used and what situations they would be appropreate for. I have some knowlage but it mainly comes from one source and would like to know how others use these tools.

There are so many similar diffusions, so there is no right or wrong choice here.

Generally, you might see built onto 4'x4' frames on a set, from the lightest to heaviest:

Opal
250
216
Light Grid Cloth
Full Grid Cloth
Muslin (bleached or unbleached)

With the middle strengths probably used most often. There are many others. Hampshire Frost, for example, is even lighter than Opal, but so light as to have limited use. I use them on windows sometimes to create a fuzzy diffuse background. Half Soft Frost is similar to Opal but doesn't rattle as much.

Of course, there are silks too, in different grades.

And the colored gels, CTO or CTS for warming, CTB's for making the light bluer. And the Plus and Minus Green Gels, Heat Shield, party colors, etc.
