Hi, I have not ridden a core so can not say much about the core, Re stability comes down to how the kite is designed, not if it has a center strut or not. Sorry cant offer much comparison. Re your post:
Yes to:
all around freeride/freestyle, big jumps, and waves and Mega lowend grunt
medium bar pressure with good bar feedback and good turning when depowered
Core has always maintained that for stability you really need a center strut, this is a piece of verbal crap
I was convinced the main reason for on off power like that was that the most functional part of the canopy.
No, this come down to bridle design/position and kite shape to get punch, not number or struts or center strut.
But how is the stability and linear nature of depower and how much boost through the kite loop
Argo is super stable, power/depower is smooth, not punchy, kite loops are good, see 7m video below. Pivotal turning depends on the speed that you turn at with the bar. Unhooking is solid.
Hope I answered some of your questions...
I think this should be under gear reviews not general.
