Callaway Diablo Octane Black Tour Driver Review – The Callaway Diablo Octane Black Tour features a slightly smaller 450cc head than the regular version, a more traditional hosel that has less offset, and a one degree open face at address, which Callaway say is preferred by lower handicap players.
Callaway Diablo Octane Black Tour Driver Review
To use it did not really look that open and the head shape was more of a subtle rounded triangle than the standard Diablo Octane Black .

The alignment dots on the face looked a bit like runway lights but we liked them and at launch the ball flew on a mid to low trajectory and that was with a 10.5 degree version.
Compared to the standard Octane Black the forged composite material is not visible on the crown of the Tour version, which we think is a shame.
However the dark looks, heavier 70 gram shaft and better sound and feel mark this out as a very good better players club. The forgiveness was pretty good and the classic lines will appeal to lower handicappers.
Great performance so it’s definitely a contender for your money.
