The Odyssey Dual Force 2 from Callaway are a development of the classic Dual Force designs and the DFX inserts. We were big fans of the DFX style and the new Dual Force 2 putters are even better as the new Stronomic insert now stretches the full width of the face. The insert is quite firm and that has the added benefit of giving the all important sound feedback that you need for holing those vital putts. Ideal for the slower greens of Europe, or if you are using a soft ball, these Odyssey Dual Force 2 putters are the best insert putters around in our view. Shame there is no Two-Ball version, but I am sure it will come soon!
