climbing skins – rat tail?

I have found a notched tail on the ski to work best…very simple and functional.  I looked at the skis you have, and it appears there is no tail notch from the pics I saw.  With a dremel, one can easily create a notch on the tail of the ski.  This would be the style of skin attachment required for the tail notch: http://www.camp-usa.com/products/contour-skins/contour-tail-kits/

I messed around with some different skin attachments last season with some working and some not.  When skins fail on you, it makes for a very frustrating day in the bc.  If one is getting deep in the bc, a skin failure can become a big issue.
