I've never flown a Tiger with the slats removed, but have been flying Tigers for a while & find that if you lock them after t/o and leave them there until the d/w checks there's nothing to worry about. I think one of the reasons the cable goes slack is if you taxi with them unlocked and they bank about.
The best thing I find is when sitting in the front seat (during checkouts for example), you can see them pop out in your peripheral vision (said the bishop...) , which means the speed is getting a bit low - a good reference on the approach.
Other than that I would wonder what the point was for a quoted 2kt diff at the stall - was the original ASI ever that accurate????
