Are you looking for Improving accuracy or just something new?
If it's for accuracy I'd suggest making sure your form and bow are where they need to be. Don't kid yourself because unless you've worked on your form, it couple probably use many improvements. It was hard for me to accept lowering my draw length as it was short to begin with, but my accuracy and confidence grew tremendously after not worrying about 10fps and accepting my true dl.
Secondly I would make sure my bow is in tune. Make sure the brace, ata and poundage measurements are close, they don't have to be exactly factory specs. Then I would bare shaft tune as long as the arrows are indexed to the specs of your bow. This will do more for accuracy than trying the new thing or jumping on a new bandwagon.
Lastly, I don't follow the archery world closely anymore, do any pros use anchor sights? I don't remember any using any in the past.......
