well i have never tried a double anything yet but i am much more partial to the diamond over the circle. i might even try a hook or rake or paperclip before the circle..
well maybe not the safty pin. that might have been a little bit of an exageration.
i would take the half diamond any day but slightly modified... imagine if you could grab the tip and strech it back a little. so the top point is about 3/4 from the front and 1/4 from the back.
there is my 2 cents
