1. I deadlift once every 3 weeks so I see no problem with it being my max effort day.
Controlled negative on max effort day - I think not.

2. I'm pretty sure both tex and I stated this is a strength exercise for us rather than a bodybuilding exercise.

3. Konstantinov rocks like Maiden!

4. I personally don't drop the bar as it scares too many people and might ruin the bar but it's going down and I'm not going to fight for any kind of negative.

IF you are using deadlifts as a bodybuilding exercise then you have a point. Using 60-80% of you max and reps in the 12-15 range might very well make sense BUT...
I have other exercises for that. For ME the Deadlift and the Squat are STRENGTH exercises. Meanwhile I treat the Bench press as a bodybuilding exercise. Go figure.
