I've been curious about this, because NGA's entry tends to be a more direct line than Ueshiba's Aikido, on average. We move off-line in some cases, but often move specifically to intersect, to the point that some of us teach making contact at the hip or shoulder to break structure.I am not sure what you mean by exiting,
Entering is definitely there on a straight line, with the idea to beat the attacker to the punch sort of speak, at least on kihon level
I don't want to say that all daito ryu technique are done on a straight line and my opinion that daito ryu teaches different ways of exposure of aiki.
