I got a Lincoln AC tombstone the other day and figured I should get a better helmet than the one that came with it. I ordered the cheapestJackson (HSL1). It came in today and I tried it out and I was shocked at the difference. I can see the puddle so much better with the Jackson. I think they are both #10 shade. The only difference I can see is that the Lincoln has more of a green tint and the Jackson has more of a yellowish tint. Is it the tint color that makes the difference or is the quality of the lenses? With the Lincoln helmet the puddle almost seems to disappear and I can't really tell what's going on with it.
