I like the feel of Super Sculpy. It is smooth and easy to form at least when new. It gets harder when it has sat around for a while but still kneeds out nicely with a little work and forms well. makes good sharp impressions and smooth surfaces. can be worked very thin.
I tried Fimo and didnt like it...it was tough to get the shape without bending or damaging previous work. Make the face and the back of the head was flat. regular sculpy is much like the Fimo and not as good as "super sculpy"
The second Dude looks great Shawn!
