Just wondering if there is a difference besides grain weight. personal preference or hardness of metal.

				The 190's are slightly harder, and have a slightly greater cutting diameter.  That's it. 
The hardness of the 160's today is about what the 190's were a couple years ago, they've all been boosted slightly.
The 190's make a great visual impression!  What a warhead. :thumbsup:
