I know this is old ... but ... the weight of the side quiver is enough to induce a bit of Kant to your bow ... some might think its tourqe ... but its not ...
In my opinion you have 3 options: Take your quiver off ... Use your sight bubble and fight it continually ... or get an off set Stabilizer set up or install a counter weight to put the ballance of the bow back to center
Everyone in my opinion should do the 3rd option anyway as the weight of the sight on one side of the riser throws the center balance off a tad anyway ... but we have all been taught to accept it and adjust ourselves for it.
Something similar to this
