The Ruby is a putter with a small grip, low weight starting at 150g and a neutral flight path. The Ruby is a great 1st putter to try, it feels comfortable in the hand and with it’s light weight it is effortless to throw. The Ruby in the Zero Soft plastic is a great choice for cold climates, and playing in winter. Also makes a great catch disc, as well as a great putter for draining long outside of the circle putts. Not recommended for putting in excessively windy conditions.
