I had another question... We'll call it Question #6:

About the roller guards... On the first run of Iron Maces, HCA went with a straight roller guard, and apparently it was chewing servings, so they modified the rollerguard to have a "dogleg" in it.

On the new bowtechs, they're using the HCA roller guard design - but their roller guard appears to be straight (not doglegged). Is that because they're using the center-trac binary cam instead of the older style offset binary (like the older Allegiances)? The Iron Mace uses a "trinary" cam which is a ripoff of the old Allegiance binary system - which is obviously not center-tracked.
