Because in 2007 Bass Cat eliminated the SS rails on Pantera II and Sabre FTD models, which customers continually expressed their dislike for this and expressed their preference for SS railing. BCB then ran an open poll which proved most preferred the rails and the results set the course and preference overall. The reason the rails were eliminated then was because of several post like yours, which proved to be an error at the time as the silent majority became voiced and ruled in their preferences after the design change.
