hi-i would say about 4 o'clock from the pin or approx 2.5 inches from the center line...stacking the cg below the pin would be a smooth reaction but less backend...for me, the ball goes fairly long, hence i like the pin under to get some earlier roll....if you have a slow ball speed, you could put the pin above the bridge and teh cg out to get more length...have several saws like this too and that drilling is great..
good luck
