Callaway Odyssey White Hot RX Putter #7
This featured a steel mesh over the renowned White Hot face insert to give a firmer sound and feel. However this slightly firmer sound did not appeal to everyone and as a result Callaway has removed the steel, but kept the idea of the mesh within the TPU insert to create the White Hot RX putter.
The other models feature a few tweaks with the classic Anser style #1 losing the notch on the top line by the hosel and the #7 and #9 models coming with a deeper face.
designer claimed that the White Hot RX is the 'softest feeling insert with roll technology putter in the market' and I think he is probably right.
Putters are very personal and with such a wide range of heads, then if you like the feel, the Odyssey White Hot RX putters are everything you could want from a quality putter.
