Where did you get the trial sample???? Can you pm me the link??
I have some opinions about this issue but i would like to play with the program first...
Also if you compaired one cam to another and it wasn't a parallel test then you cannot say for sure what the results are...more agressive flat to a mild roller....
One thing to figure in..... If you loose a lobe on a flat tappet cam and need to remove the entire engine,dis-assemble, remove cam bearings and freeze plugs hot tank,grink or polish crank, new main and rod bearings...... The $600 for the roller starts looking like a deal!!!!!IMO
