In my opinion, (and this is something I don't know a lot about) the click wrench is a more exact way of torquing things down. As you pointed out, the bending beam is for smaller bolts needing less torque. To torque an 85 pound I start at 65 in a criss cross pattern, then to 75, then to 85. (The torque is determined by the lug nut size). 7/16 80 pounds. 1/2 100 pounds etc etc. I go to 85 because the number is easy to see on my wrench.
ALWAYS STORE THE WRENCH WITH THE TORQUE RATING SET AT THE MINIMUM which in my case is 20 pounds.
I recommend getting it calibrated every few years.
