We have not manufactured he Outburst for years and the Glider X irons went away a few years ago. both were super Ultra Game Improvement irons. At level of forgiveness, you would not be able to tell the difference in performance, even thought the old Outburst was 1328 MPF and the Glider was 1209 MPF points. Ralph designed those to be the Xtreme in playability. Personally, I think the Glider better suited more players because of its sole design, combined with the stability. My suggestion is to hold on to the Gliders. They don’t make them like that anymore.
Thank you just saw em for first time as a set and thought I might better myself
