Never shot a Whip. They look like nice enough bows though.
All I know is that I wanted a Kanati for a long time and now that I have one it's even better than I expected.
As far as speed is concerned, my Kanati is one pound heavier than my Pittsley Predator Recurve(the one I traded for the Kanati, with some "boot" to me
) but the Kanati was only 3-4 FPS slower than the speed demon Predator, with the same weight arrows. I shoot a fairly heavy arrow at a modest draw weight and a rather short draw length.
The Kanati is what I would call an extreme reflex/deflex bow and lacks nothing in the performance category nor in the shoot-ability category either.
