Also I'd like to add that I use a Tru-Glo sight as well and see no reason why it shouldn't work for you. They (Tru-Glo) generally have sights with good size sight rings for extended range pins. So the fact that you are having trouble getting the 10yd adjusted tells me something is not right. It was said eariler and don't take offence but make sure your adjusting it the right way. You want to follow you arrows, if your arrows are impacting high then move the pins up if the arrow is impacting low move them down. Left and right are the same thing.

I am very particular about my sights, I shoot a 20-30 and 40yd pin. I want my middle pin (30yd) to be right in the middle of my sight...perfectly centered. So I adjust the whole sight ring first to make sure my 30yd pinis in the middle. It takes some time to do it but once it's done you will have a better sight picture when hunting and all of your pins won't be bunched up either at the top or bottom of the sight ring. They should be right in the middle.
