Agree with much of that Rob but the specific point I'm flagging (albeit maybe slight Devils advocate) is rangefinding.
The questions I would pose are:
is range finding currently a competitive aspect of FT (assuming you understand how to rangefind)?
If the answer is no then why bother ranging at all?
If the answer is yes is it reasonable to ask if 80 mag and above (there is a 100 mag out there now) going to remove the competitve element?
