I have 2 newly used Tibhar Rapid D.Tecs Max (red and black) rubbers.  They were only used ONCE in a session today on my new Samsonov Alpha SGS blade (similar head size to TBS blade and Acoustic). The rubbers are now off the blade and will no longer be in use, until someone buys them.  Rubbers come with plastic protection sheet on them.  If anyone wants them, they can have it for $33 shipped to the US/Canada.
