DK has it. The laminations on the 160 El Grande are a bit thinner to lower the weight, but they are the same profile as the 200. The 160 standard is the same thickness as the 200 but smaller profile.
The hardness difference between the two, the standards are about 51 and the El Grandes about 52, not much difference. And while the El Grande looks much bigger visually, the actual cutting width difference is only a mere 1/16" of an inch.
Both great heads, you can hardly go wrong with either.
Hope this helps, Tim
