My thought on top weight is since you sound like a stroker, you'd want more top weight to help with hitting power. On pin placement, I believe putting the pin 3 3/8" from the your Positive Axis Point and Center of Grip and 12:00 aobve the Center of Gravity will maximize hook, won't help with length. Then you may need to polish/bring-up the coverstock. Feel free to correct me because I'm rusty on some things.
