The issue with some of the info provided is that advertised duration means nothing. Compare duration at .050 and if possible compare the .050 to .020 specs. LSA also isn't mentioned and make s a huge difference in the way they idle.
For instance advertised 284 and at .050 206, etc..
The cam you typed in the first post is 212/218 duration @ .050. 444 lift. 110LSA
Check out these cams. This is in the realm of what you are looking at. The Howards for example claims "mild idle, good low RPM power"
