As far as Blade Triggers go, if the 2013s are anything like the 2012s, I would say they have a bar pressure that is medium to heavy. The 2012 Trigger feels similar to my 2010 Epic Renegade and the kites look almost identical. If they don't give you tennis elbow, they are bound to give you intersection syndrome.
2010, 2011, 2012 Triggers all have light to light medium bar pressure at most.
I've been kiting for 8 years and have flown lots of kites.
In comparison to twenty other kites, Triggers fit right in with the lighter group.
The Epic Renegades are also light to light medium.
The Renegades are similar to the Triggers, same designer but there are definitely differences in several areas.
Triggers jump a little better and Renegades are a little better for surf.
Renegades have a little more bottom end and Triggers have a little more top end.
Triggers are set up and marketed to be a do it all kite.
Renegade was tweaked to be a surf kite first, and an all around kite second.
The Obsessions pressure must be super, duper light to give the impression that some of these others are heavy.
