I basically agree w/ everything you said, I was being more figurative than literal. IIRC my impact is only about 400 lbs forward as well. Of course no impact wrench actually supplies that in actual torque, it's a torque equivalent resulting from the rotational "inertia" imparted to the fastener by the tool. Poor man's impact wrench is a box wrench (or solid breaker bar w/socket) and a hammer, and can perform wonders that alot of straining in the form of pure torque cannot.
I guess my point was really about how you can't really control it all that well. To borrow from your example, if you happen to know your impact is going to give you the equivalent of 200 ft-lbs pretty consistently by beating down on it, exactly how much do you beat down to get 118 ft-lbs (without benefit of a nifty dial gauge)? Or, in the process of not wanting to over-tighten it, you quit before it's actually tight enough? Takes a fair amount of practice/experience with your impact to "feel" that 75% or so yield point, and I'd hate for someone to get overzealous with some King Kong impact and gall threads, maybe even shear a bolt during the learning process (possible, if it had corrosion and/or stress fractures already), or potentially even worse have a blade come loose.
That's where the torque stick gives you the best of both worlds.

P.S.- The golden rule my gearhead buddies and I have used for years is: The correct torque for any fastener is precisely a quarter-turn before it snaps

PM me. I build a jack system for the front end that works really slick. Rev two would be even better.

I have used an electric impact for many years with absolutely no problems. I have a feel for the tightness, once it starts to bang I stop when tightening. I have never checked the torque, it is a feel thing you become familiar with.

People don't realize the vibration from the impact works at loosening the blade bolts so much easier than steady hard pressure.
