which gel to use for green screen?

besides in one shot the green screen will be on the floor: the actor will be hanging from above and the camera on a top angle above him. in post, we'll try to achieve the effect of the actor spinning down in a black hole as his figure will become smaller and smaller. if on set i'll light him just from one side would the final outcome look weird considering that the spinning effect will be achieved in post? i mean the light on him will be always from the same side no matter of what his position is while spinning? of course it is not going to be a naturalistic shot, actually it's all the opposite, anyhow i'd appreciate a lot any suggestion from more experienced cameramen in this domain.

As for how you light the person hanging from whatever, it will look very strange the way you describe. if that's what you want, fine. If not, perhaps a sort of poor-man's process kind of thing in the studio would work.

Try to have your compositor on set, so they can keep an eye on the shots, and the eveness of the green screen.
Use space lights by the way. I recently saw 3 used on a white room video and it took 20 minutes to have them up and evenly lit. I don't know why I didn't think of that earlier. Kino's will work, but the falloff is fairly quick, so you'll need kinos on all sides of the green screen which takes time and lots of kinos.
