I play with extreme western grip, so I get control from spin and lead at 12 enhances control while adding power to my game.
If you hit with average spin or if you have flatter strokes, I would say go for lead at 3 and 9, which I also liked quite a bit. Control is great and stability is improved.
The key to customization is start experimenting until you find something perfect. Don't give up! Good luck!
