I'm not sure if I have any more experiance than you, but I'll give a little of what littleI have to offer.

I like a single vertical pin for hunting, multiple vertical pins cover too much of what your trying to aim at once you get past the top pin.
For hunting with a verticle an adjustableslider or single pin is the only way I'd go. I like being able to line the single pin up the leg and aim at the nuckle, it works well for me that way.

For a multiple pin sightI like a horizontal pin with a .029" for the 20yard pin and .019" pins after that. Tru-glo used to sell one that way andI made my most recent sight aqusaition that way by starting with a .019 sight and adding a .029" for the twenty pin.
The .029" willshine more in a low light scenerio and the .019" block less of the target at furtherdistances.

I'd recommend you look at the tru-glo'sand cobras.

If your willing to spend a little more the extreme RT-900 looks like a lot of bang for the buck -
