Anyone have any experience with the Paulimoto clutch spring spyder. One seller says "The Spyder Spring Retainer adds further functionality and beauty to Ducati's dry clutch. The unique design replaces the six separate retainers into one beautiful billet aluminum item. The design maintains a better parallelism between clutch plates and pressure plate resulting in more positive clutch engagement and a quicker response. Machined from aerospace grade (6061-T6) billet aluminum." Seems like a decent design idea, but I'm wondering if you'd really be able to notice the difference. Also on a related issue, do billet pressure plates perform any better, due to greater stiffness?
