Been there done that. I was shooting 28" for a long time, and then got a lot more serous about really fine tuning my form this year. Now after working on my form and figuring out I had a 29 1/4" - 29 1/2" draw I am shooting more consistently. I was shooting with great accuracy some days, but would have real off days. Now I am mostly on with the long draw, and when I am off I just pull back farther and I am fine again. Fortunately my arrows are carbon and my bows liked longer shafts with the heavier inserts and points I was shooting. About half my shaft are now target arrows setting right up on the shelf and I am just finishing setting up hunting arrows tuned with longer shafts and a little lighter points.
