The Spin is an understable putter that debuted in Electron in the 2016 Circuit Player’s Pack.
The Spin has a deep profile like the Ion and Anode, which makes it great for glide-filled lofty flights. Its controlled understability makes it suitable for both new and advanced players alike.
Flight Ratings: Speed 2.5, Glide 4, Turn -2.5, Fade 0
About the plastic: Neutron is an Opaque blend of premium polymers that offer extremely good durability and hand feel. R2 only comes in black with a white overmold. These have a decent amount of flex to them, but are on the stiffer side of something like an Innova Star plastic. Typically this is a plastic that is “true to flight numbers”, but it still depends on run to run.
