No no no no no.... Its not about absolutes this way or that way. In each 
of the possible mediums you could achieve the same degree of control. 
There would just be different demands placed on you to achieve that 
control.   And besides... you guys are both forgetting that this 
particular analogy went to describing the amount of time available for 
steering a bat into a speeding ball.  In that analogy the 
weightless/weighted bat is far more appropriate to use then the degree 
of resistance of a given medium... unless you applied that same to the 
speeding ball... in which case you will have only introduced a moment of 
slow motion and othewise have changed nothing.

The weightless bat...yes... ever tried smaking a whoffel ball with a 
whoffel bat ??... much easier with a real bat... gee.. I wonder why ?
