remember to test your roll over star inserts before you install. you dont want to mess with that last minute. what I do is take a pair of wire cutters and cut the bottom lip off the white star stem then I can drop it in the hole and take it back out to see if the star is clogged with clear. if you need any help drop me a line.
as for the grading system, this is my guess from what I see every day, that they dont grate them gold or silver based on the clear, its based on the print I think, because I cant see any diffrence in the clear between any of them that is not random, although where is good old loudmouth stu to set me straight. I dont come on here much, havent seen him lately. and I say that with love, its just words.
