You get the option of a lightweight skeleton spool (for light lines and quick response to the anti-backlash control) or a full-capacity spool (for heavier lines) when you buy one of the top-end Marado Generation baitcasters ($129.95 to $139.99) Centrifugal, magnetic anti-backlash controls are featured along with six stainless ball bearings, contant anti-reverse and a titanium-nitride coated aluminum-oxide line guide.
