Problem is that the larger diameter arrows sit higher on the rest. Solution is to change out the sight so that you have one for each arrow. It's a simple solution if you have a dovetailed sight, more complicated if it's direct mount unless you've got the new modular SureLoc QC2 and a second module.
But even then the nocking point is going to be too low for the larger shaft.

This is why most serious target guys have 2 different set ups one for target and the other for hunting.
