I must suck at describing things...
I am at a loss as to how this is functionally different or in anyway better than what I suggested in your log and you said was too much tension. It must have been misunderstood, so I'll try again.
Loop the bands around one peg. Then pass the band under 1 or both of the other pegs then up to the bar (an alternate option is to pass one section under one peg and the other section under 2 pegs after the initial looping around one peg). What I am describing is not wrap the bands around the pegs twice nor is it double the bands over the bar.
What it will look like is: the band comes out from underneath one peg and goes straight to the bar (this is just one loop of band), the other end is passed under one or more pegs and is around the last one.
I'll try and take a pic/vid of this set-up in case this doesn't make sense.
