Viper HT

  - Snake Eyes
A hybrid-to-hollow-cavity back set, the clubhead body is cast from 431 stainless steel and the face is H420 high-strength steel (50% stronger, which allows the face to be 30% thinner than other irons).

The #3 and #4 are true hybrids. They progress to the #5 and #6, which are hybrid-irons. The set rounds out with #7 through wedges as hollow, cavity-back irons. All lofts in the set feature hollow technology with the H420 face.
