Force Field Multi-Power question

[Colossus]

Steve,

I know if you have a multi-power slot that is not fixed in Force Field it needs to keep the same PD/ED ratio. Is it legal to buy to non-fixed Force Field slots (say Force Field 20/0 and Force Field 0/20), each slot would cost 4 points and you would control the amount of Force Field vs. each attack.

Just to make sure I understand you, let me stat out what I think you're asking about (forgive the lousy formatting):

20 Multipower, 20-point reserve.
4m 1) Force Field (20 PD/0 ED)
4m 2) Force Field (0 PD/20 ED)

That's definitely a legal construction. It would, as noted, allow the character to control how much of each FF he had working at any one time, to a maximum of 20 points' worth of defense. The only difficulty would come in that most GMs won't let a character switch a Multipower more than once per Phase (see Rules FAQ), so it would take Zero-Phase Actions in two separate Phases to switch the allocation of the Multipower completely.
