Erson vs. Comp Cams

I have 1:5 ratio Harland Sharp Rockers and do not really want to buy another set. They work really well for me as in they don't break and they hold the lash really well.

Erson 252/256 @ .050", .430"/.430" lobe lift, 645" lift
174/178 duration @ .200", 112 LS.

Comp Cams 252/256 @ .050", .418"/.423" lobe lift, .627"/.635"
175/179 duration @ .200", 112 LS

IQ52, i've never seen duration at .200. If both cams have the same duration at .050 but differ at .200, what does this tell us about a cam. :coffee2:

Longer duration at .050 means it's opening the valve quicker. More area under the curve. Harder on the valve train components. More power.
