Latitude's Mercy putter in Zero Hard! The Mercy from Latitude 64 is slightly overstable at putting distance, but driving is where it's at with this one! The Mercy can take a full-bore rip and hold its line. Extra beefiness at the outer rim and a nice blunt nose help achieve this tasty flight. For those who know how to drive a putter -- show no Mercy to your competition!! The Zeroline Medium plastic really is the happy medium between Soft and Hard Zeroline. It has a firm feel with plenty of grip mixed right in. Zero Line Burst is a very unique looking plastic that has a mixture of two or more colors bursting from the center outward. All colors offered are the primary base color only and each one is entirely unique!
