Punisher and Intense will/can FLIP; Slay/R is for one complete step down in oil handling and hook potential from the Punisher and the Intense. I think the Intense is a slightly stronger overall, in that it handles more oil, than the Punisher. All hit BRUNSWICK hard. Intense and Punisher have the potential to cover a lot of boards. Intense can handle carrydown, more than the Punisher, depending, of course on drilling and hand.
FYI I have an Intense and a Slay/R; teammate has Punisher as do several league members.
