Single or Dual Pattern Cam

What cam is better for the building of my small block? One of the posts earlier suggested a LSA of a 108*. I went through some of the lunati cams and I seen a cam with 275* and 220* at 0.050", I think that the lift was. 475 Both the LSA and ICL were 108*. I know that I've been given suggestions on a cam which I'm going to write down that information as well, wanted to know what you guys think about this cam.
