HHA is a good single pin if you like single pin sights. For me I like multipin sights, one less thing to think about and perhaps have to move at the moment of truth when hunting or like some hunters I know miss because they forgot to adjust their sight when the big buck wa there.
Spot Hogg are perhaps the toughest multipin sights, Copper John are tough as well.
Trophy Ridge, TrueGlo, Apex all make some good sights and some that work but are not the greatest for sure.
For multi, I love my black gold. When I got it, the only sight that won't halo in bright daylight, and will last long enough to shoot at last light. All metal built, fully customizable and don't cost an arm and leg,

For the price it's hard to beat that great Texas based company
Iv been shooting my 5pin for 6 years now and really put it to the test... im not easy on my bow what so ever... its been ran over, dropped out of a 20ft stand... twice.. and tossed into the back of my uv without a case just about every time I hunt... think it may have cost $100 and well worth it. low light is no problem I even shoot pigs outa nothing but moon light pretty regular
