Another thing you may want to consider on your sight pin is a good way to illuminate it. Hopefully a variable light source.
Learned this the hard way last week at the first night of the indoor league I shoot in. Had shot there during the day with my scope set-up ( circle reticle ) with no problems, but shooting at night without the little bit of daylight that filters through the front of the shop changed everything. Couldn't see my circle very well.
Just another reason to spend some more money on archery goodies.
