Whats so good about OI or Orginal Inferno? I have a chance to get one at a cheap price NIB. I just want to know whats good about it. Im gettin the Radical sometime this week and i hope it can fulfill my Heavy to Med ball and i have the Red Zone for Med to Light and where would the OI go? Also i plan on getting a Power Grove drilled weak or all backend for dry. I've heard good things about it.
