All I know is that in the normal Bell 206 L4, if you are not careful about your weight, and you try to take off into a hover too heavy at a high DA, you will find yourself spinning as soon as the skids leave the ground with the pedal all the way to stop, and with about only 80% power applied (TQ), bringing it down again becomes very tricky, if you try to do anything but roll the throttle off.
There is a beautiful video of this, pilot who is taking off from high mountain, starts spininng a foot off the ground, doesn't have TR authority, but has enough power to climb vertically (while spinning of course) then he dives it, recovers control for an instant at about 50 feet, only to loose it again and crash.
Don't know if you can call that LTE, LTA but whatever it is its a very dangerous if you are not careful.
The 407 TR, well that is a completely different story, it will get you out of most trouble, but it will also reach it's limits at altitude if you are not careful.
