Bottom Stamped Discs - Need something different? Try the BS "bottom stamp" disc from Innova. They have a blank topside and a small hotstamp on the underside of the disc.
BS Aviar Putter - (165-175)[21.2cm] - Based on the Aviar mold but without the bead and with a softer plastic to stick to the chains. A little less overstable than the regular Aviar. Probably the most popular putter and approach disc in use today.
