This discussion is talking about apples and oranges. Take drivers' license courses. A simple driver's ed course gets you a reduced insurance rate but isn't required to get a driver's license. Then you can spend a lot and go to one of the "racing" schools to get a race car driver's license.
It's an analogous situation to the discussion about levels of classes for CCW. Except having a driver's license isn't a right supposedly guaranteed by the Bill of Rights while having firearms is supposed to be a right. Yet the "pivilege" doesn't require a class while the "right" does. Seems backwards.
I'm with the group that says the minimum class requirements per law to qualify for the CCW should be enough. High-Speed-Low-Drag shooters, just like the race car driver equivalent, should get the best follow-on training they can afford. Note the key use of the term follow-on training. No one should be required to take a LFI course or anything similar to qualify for what should be a right in the first place.
