he Banger GT (Groove Top) is a unique Discraft putter that has a Groove around the top and a large bead that help provide an enhanced grip. The GT is very popular for hyzer putts and offers a consistent release. It is a slightly overstable putter with a very straight flight path. The Banger GT is available in the inexpensive Pro-D plastic and the Soft X-plastic. For putters, it actually has a fairly low profile and isn’t as thick as some.
