you know .... that's my theory on smoking and tadpoles too
....
you mow down the infantry and what's left are the special forces
....
only the best gets through .... 
the others don't buy that though .... 
your analogy sounds like this to me: gunning down the enemy is
less effective than hand-to-arm combat. by this guns = smoking;
hand-to-arm = soy.
you've got your logic wrong. smoking is far more
detrimental.
