what would be the best tradeoff. a jet effect in the hosebarb. or a larger hosebarb with multiple small jets inside the waterblock. (i feel again, that i will prolly be the only one understanding this mumbo jumbo)

remember that water-in always equal water-out.....
so no matter what you do, do not restrict the entry or the exit.
this design relies heavily on surface area and turbulence, and turbulence is directly proportional to flow-velocity, not flow-rate... there is a big difference.
I found that by having the inlet right on top of the core (hotspot), I get the "eye of the storm" syndrome. Meaning that right in the middle, there is barely any relative movement. the most turbulent region in such a configuration would be in circular patterns out from the middle, with more verocity as you approach midway between the inlet and outlets.
Virtually the same problem high density heatsinks have, when the fan is right on top, centered to the core. That's why a side mounted drafting fan config, usually gives better core temps, in heatsink world of coarse.
