Not sure if this would things with your sight picture or not, but are you sure you're shooting the right draw length?
For 99 out of 100 people that are 5'7" tall, a 29" draw length would be too long, even if you're shooting directly off the string with no d-loop. It's possible you have exceptionally long arms, but you might want to analyze your form to be sure your DL is correct.
For example, I'm 5'8" tall, and I use the 27.5" module which puts the string at my nose with my nocking point directly below my right eye, and then I use a 1/2" d-loop which allows me to lock my anchor using my index and middle finger knuckles locked in behind my jaw bone.
This *might* help your sight picture with longer range pins as well, as it will change your relative peep sight location. Either way, proper DL is always a good thing to re-evaluate.
