I have only owned two 6.1s ever, one was the classic and one was the "si". The classic (black buttcap, newer, matte finish) was alot lighter and less stable. The older si was white buttcapped, shiny finish, swung much heavier and solid as a rock. It swung so heavily that it was cumbersome for me, but was much much more solid than the newer one.
