Not so sure I would just jump into doing Negatives right away especially if you have never trained in that format
I too think, if one uses negatives, it is something for more of an advanced lifter who has had enough heavy lifting under their belts, to have trained longer term the tendons and ligaments that take some of the heavy wear and tear on using these higher loads.
Negs can be an almost, out of control lift and one should certainly have spotters for one, and know what they are doing and have enough time under the bar to know exactly how to use them.
One can go extremely far, and get quite close to there potential, using positive multi rep and set routines on the big compounds without needing all that extra stress stuff.
