I have been searching the posts in hopes to find a comparison to for a 74 LD and SD. I did find that the LD the thickness can be deceiving with it's thickness. When going through the 74's I would find this thick ones and sort of get excited, I know it doesn't take much
, but is there an easy way to tell the difference between the two and i take it that the the latter 2 of he three pics are just common LD's. Thanks for the help.
