Favorite Big Block Roller Rockers

When I look at Mancini's website and look at the aluminum roller rockers they say right on the website that they are made by Harland Sharpe. So wouldn't be bad thing as for as I can tell. The stainless steel one's say PNW on them on the site picture. Thank you all for the information so far. See some solid options

Also, what is the main advantage of going to 1.6 rockers?
