Another option available in late November is the $250 Barnett billet aluminum clutch basket that has stainless steel inserts covering the surfaces where the friction plate tabs impact the basket fingers. Used with aluminum plates, you'll get both the weight savings (and a quieter rattle) and a basket that resists notching. Hopefully, this means an extended clutch basket life because only the worn plates have to be replaced the next time around. So overall costs are less. The inserts are riveted-on so it may be that they can also be refurbished. It can be used with steel plates as well.
This seems like a good solution that offers an obvious advantage over more expensive competing aftermarket alloy baskets that claim that their hard anodizing (a surface treatment) reduces notching.
