you should be able to push thru the stopper system.. if you cant, then whats the point?
The point of the stopper is to stop the bar when you adjust it to your desired throw... not sure why you would want to push through? If its for safety reasons, both the Slingshot and Liquid Force pulls the c-loop line through the stopper when the safety is pulled. To each his own but its annoying to me to not have a 'lock'.
I personally agree with bleighty and disagree with sbkiter and North. I like to be able to rest against a stopper BUT be able to "push the bar out through" the stopper in a gust (such as on the North 2007 bar and unlike the upgrade on the 2008 bar). However, just as bleighty and sbkiter don't agree on this, this ability to push through the stopper is subject to personal riding style and taste. Given an "push-through"-able stopper or give me death. In the latter case, I would not use the stopper.
