It's awesome...
"Normally", which means I just started using them again

I use a Cokin P holder, Galen Rowell Warming Circular polarizer, and a Galen Rowell 2 stop GND (stacked) when necessary. BTW- The Galen Rowell warming circular polarizer kicks rear. However, when I bought the 3-stop reverse GND I bought the 3x4 "card". I did that because wider than 35mm shots start to vignette in the corners. It's not really vignetting so much as the holder gets in the way. Forget even using a holder with the 14mm lens. I was pleasantly surprised at how easy it was to position the filter. I've seen examples where the photog stacked the "cards" and held them together with clips rather than use a holder. Plus... if I ever actually shoot LF I'll be able to use the card with those lenses.
I spent a day in Big Bend with nothing but a 35mm lens and the two filters listed above. Even high noon shots were greatly improved with the filter combo.

PS- the GND in ACR works pretty well but the real deal lets you capture the color. If you need to tone it down a little more the one in ACR works pretty well... Not a save-all but certainly a good tool
