Tatard : 88160 pts (28/11/2012)
Go for the upper triangles, where the 3 of them meet and activate before impact. Key is to shoot quickly to maximize collateral. High 70s routinely, once in a while a GS..!
Here is a pic, just in case..
Tatard : 110400 pts / 3 birds (27/04/2012)
1st goes to the closest stone of the lower stone circle, explodes at contact, goal is to push them as well as the other ones in the above stone circle in a North-East direction. 2nd to upper stone circle, same scenario, but goal is to push them East. Wait a few seconds, a bigger cloud should have slowly formed above the top glass cubes in the back, shoot 3rd in the middle of that cloud.
Here is a screeny in case the score doesn't seem legit..
