Big Pistons, I tend to agree with most of what you say except that we teach our pilots, in Cessna 310R's, to rotate at TOSS(takeoff safety speed)and to keep hands on throttles until blueline is achieved at which point gear is selected up. This Gear Up point is the Go, NO Go, decision point as far as continuing is concerned. Any engine failure prior to that point is going to result in the land straight ahead scenario. There is one other thing that we do. Keeping in mind that blue line is calculated for maximum weight we have calculated lower blue line speeds for lighter weights by interpolation. The only reason that I have pulled you up on this is that I'm sure you will agree that trying to hold a C310R on the runway till it reaches 107 kts and full power is a mission that some pilots may not be able to handle without damaging the aircraft. Also this is not the technique called for in the POH.
