I was referring to dromaeosaurs in general. I think the lil'uns could (and did) climb and jump out of trees, but as for the big'uns (_Deinonychus_ and their ilk), probably not.

I'm not sure...
Those hindlimb wings ("butt-fans") look maladapted for running - never mind building up speed for ground-level takeoff.
Sure, Microraptor was utilizing its feathers in an aerodynamic fashion, but it is not at all obvious that is was the type of flight that you are thinkng of when you say it was "incapable of a running takeoff."
It _would_ be nice to get full fluff, complete with tail fans and wings on the JP 'raptors.For that matter, it'd be nice to get a T. Rex that could rightfully whoop a Spinosaurs arse. Must've been too lazy after all it's scavenging on that carcass before the humans disturbed it.
What would _Velociraptor_ use them for...?
Sure, they could get up in trees, just like goats can, but they aren't built to habitually utilize arboreal perches in their prey aquisition.
I'm not clear what you mean here. When you say "leaping after prey" do you mean leaping off the ground in pursuit of terrestrial prey? If so, why is this better than just simply running after the prey (i.e., the "old-fashioned" way)?
