Any reason we don't hear more about the Comp XFI lobes vs the XER lobes? They look to be a little steeper and a little more duration at .006 than the XERs with very similatr lift. I have someone asking me about a 224/230 cam and he is trying to decide between using XERs or XFIs. He is switching from a TSP Torquer 2 wanting more low rpm torque. Heads are TSP LS6 S2. These are what he is trying to decide between. Is there even enough difference between these to notice any difference?

_____.006____.050____.200_____lift
XER 273/279 224/230 146/151 .581/.592 +1
XFI 276/282 224/230 147/152 .600/.604 +1

Mix them both in a blender and what you get?

224/230 .600/.592 (choice of LSA/ICL)

I might add that this person called a well known shop (sponsor here), told them what he had, what he didn't like about his set up and the XFI cam I listed is what they recommended he switch to. I forgot to mention it will be a 112 LSA. With the +1 that would put it on a 111 ICL.

I'm SERIOUSLY considering doing this as well.

Just want a little extra kick in the low end from where I am now.
