I totally agree!
I was service manager for 15 GMC or Chevy 1 1/2T to 3T tow trucks and although they had 3-finger OE clutches at first, we found that the drivers quickly got fatigued with the HD clutches and we changed them all out for Diaphragm-styles that took a lot less pressure to disconnect.
It was a lot less wear and tear on the whole driveline - u-joints in particular.
The Borg-Beck styles had a lot of hold, but they were hard to hook up softly with a vehicle in tow and the heavy weight of the truck too.
Now - if your vehicle is lighter - there's a lot of chirping and jumping and wear on the clutch linkage too.
I've seen the frame-side ball rip off the frame from a lot of mechanical disadvantage.
Lifetime-wearwise, the diaphragms outlasted the Finger styles especially when you know a 13" 3800lb Hays Invader Clutch is what you're lusting for but it just tore things up.
