Sticklebricks, classic or dud?

lego hurt more if you accidentally stood on it in your bare feet, but you could make so much more with it that it wins anyway.

My son has just been given some Stickle Bricks for his (second) birthday, and they're great. Probably better suited than lego to little hands, and I'm enjoying them even more than him.

Also, light enought that they don't hurt when they're thrown at you.
