Derwent Water Soluble Sketching Pencils

I have had my pencils for sometime and have never really used them with water.  After being asked if I used water with these pencils, my curiosity got the better of me and I decided to do a simple play.

What I found I like is the results being subtle - at least on this paper and using the Light Wash (HB) that I normally use.  Using brush with a little water makes for a nice tone but leaving some texture showing as well.   I'm sure with the darker pencils, one could achieve some dynamic results combining dry marks with areas washed over.  I'm definitely going to play more using the softer pencils considering I love the Ink and Wash look.  Why I haven't up till now is anyone's guess :-D
