What type of bar pressure? Constant or high pressure?

My waroo doesnt have much at all... much less than my 15m c kite... no stopper so it's constant light pressure, but thats a function of the bar (no stopper on my bar). I can hold the bar in with one hand easily.

The crossbow (the version I rode) on the other hand has a LOT of bar pressure. I get tired quick trying to turn those things. I can't imagine trying to ride one without a stopper! I brought it back pretty quick with pumped forearms.

I dunno anything about the bar pressure of other flat kites.
