I think that Spot Hogg is overpriced and you can get the same number of pins, birghtness, and a level with a different sight for less. Cobra makes a great multi pin sight called the boomslang. I'd get the 5 pin version. You'd like that a lot.

Personally, I use the HHA Optimizer-Lite Ultra DS-XL5519. I would only recommend this sight if you shot a lot of 3D. Shooting 3D with this sight will get you used to adjusting it for the yardages. If you are not used to adjusting it, you will forget to do it in the stand. Still, as far as single pins go, HHA makes the best.
