I have had a couple of Leopards that I cant seem to find anymore... they say Pro Line on them, but they aren't like the new Pro Line Leopards. It says Ultra-Long Turning Driver on it and "Designed for Professionals". It also has a big Innova bar stamp on it. The plastic is also different from the new Pro Line Leopards. I found another old Pro Line Leopard, but it is the clear Champion like plastic. What is this plastic? What that I could find now would be like it? Thanks in advance!
