What Discraft says about the Roost:

The Roost is a deep putt and approach disc with a hand feel that immediately stands out. It takes up more space in the hand than a shallower putter, giving it a substantial presence at release and a feel that players will notice right away. In flight, the Roost leans overstable, making it a dependable option for players who want a putter they can trust to handle torque and finish with confidence.
