I was gunna say before that, in my experience, 99% of lefties bowl in-swingers to right handers, so the edges were rare, and unless the in'swingers were MASSIVE, LBW wasn't really a problem either.
Also, lefties seemed to always be slower than the right-hander up the other end.

Man, I loved 'em -- if they started the innings with a "7/2" field, or a 6/3, I would also try to smash anything on the stumps through the on side, because if I was hit on the pads, the ump usually
said: "nah, too much angle", or "nah, pitched outside leg."
I also felt safer against short balls becuase they moved across the front of my body toward the slips, so I could pull stuff with no fear of getting hit.
