+1...DL of the bow will not change, but your overall DL will change with the addition of the D-Loop...you should anchor to the same place, so with the addition of the d-loop it may be nessecary to shorten your draw a tad, or you will need to find a new anchor, and leave the DL setting the same!Your draw length will not be effected, it will remain the same. However, your anchor point will be a bit different depending on the length of the loop.
