and then I said "duuhhhh...."

[Lance Lafargue]

If you increased let-off and did little to the drop, the drop would be
less, so then you would have less "bump" feeling at let-off, less friction,
seemingly more control.  All of these translate to less work for the player
and feels "lighter" to them.  Just a guess with the info you gave. 
QUESTION: If you increased the blow, how was the aftertouch?  Did the
player notice a change in that?
