I used a one point mid 2005-mid 2006 used a Putt'r first run stamped Soft X I had wone and the only flaw is the plastic the mold is made in, make the Putt'r in standard Pro D and it would work. Discraft had a soft Pro D made for a single first run/test flight right before the Soft X came out. The Flaw with the plastic is the mod gets a concave top to the lid after a hot temp 90+ F round to the lid so the plastic looses all glide and due to the shape of the rim/wing being wider at the bottom then the edge, the lid can have more power in putting to the mold then most lids so it is easy to fly past the basket. The flaw means the mold is for those who do only chest spin putts with 0% power using mega amounts of snap like putting with a stable Ultimate disc or heavy larger catch disc to get the disc to fly right. I gave my Putt'r max weight to a then Girl now women in 2007 when she used Putt'r only after they had broken in, she was putting with the same style I mentioned already only she started from the waist and finishing at chest height when at release. Before that she was using Pole Cat that was So unpredictable in any wind at all being an E.D.G.E weight 140 gram disc.
