ive recently been buying Rieger cane. I buy it gouged and profiled, and i think that Rieger has set their profilers limits too narrow. That is, the distance between one collar and the other collar of unfolded cane is closer than what im used to. Now there is an immediate advantage to this, after forming the reed less material needs to be clipped from the tip in order to open the reed. That extra can length is instead now part of the tube. So the overall reed is longer despite where the tip is cut. For those players who are always sharp, this may be an answer. It can be as dramatic as choosing a longer bocal but instead having the ability to shorten it by reaming.
