Quite the opposite actually. Think of it like a tire. A tire made from a softer material (ie. in terms of durometer) will grip the road better (there is a logical limit of course, as it needs to have a degree of durability or it will wear down like crazy). A bb is the same way. Soft buckings in my experience provide a more consistent spin.classic said:Really? I just figured set up for right around 540 the soft wouldn't be firm enough to effect the BB. Thanks for the heads up Yankee!
