I get the string right behind the 1st pads of my fingers(I shoot a tab,also).Draw with a straight wrist the whole way to your anchor.Alot of times,people bend their wrist inward resulting in torquing the string.Hold anchor for a split-second and relax the fingers smoothly and follow-thru with the shot.Also,pull with the back muscles-not your arm.
Forgot to mention-those 2016's may be a little weak for your bow.I'd try a 2020 or 2117 shaft.
