The Butter is a straight flying putter. It is beadless and has a straight to stable flight. The Butter is a great choice for putting and throwing if you are just wanting a simple, straight, glidey straight-flying putter. It has a comfortable feel with the beadless rim allowing for a smooth and consistent release.
Flight Ratings: Speed 2, Glide 3, Turn 0, Fade 1.
About the plastic: STEADY is a durable and flexible premium plastic that guarantees a nice easy grip in all circumstances. This plastic is as durable as it is beautiful, and feels comparable to something like Kastaplast's K1 plastic.
The Butter is kinda like the Innova Aviar. It feels deeper to me. Plastic is great tho!
