I still hold the question open to all.
But to reply to Kurgan, I would say that Obi-Wan in TPM only used the other colour (i don't rember, does he switch from blue to green?) because he has to, he looses his blue one down the well and has to use Qui-gon's green one or else die.
And this is basicly the same in AOTC when Obi-Wan and Anikan use different coloured ones to what they usually would use because they have to. The bug things (any know the species name?) take away Obi's and Anikan brakes his on the convayer belt. Then in the fight, they have to use a lightsabre that they are given.
So on the type of force used, it doesn't count in those situations. It is like saying that in AOTC when Anikan uses two lightsabres, he is using Living Force and Unified Force at the same time for just a few secons!
Also what is the difference between Unified force and Living force?
IM NOT GOING TO BE ON THE FORUMS VERY OFTEN NOW! I MIGHT BE ON TIME TO TIME, BUT IVE BASICLY GIVEN UP THE FORUMS NOW!!!!
