I order all my Spot Hoggs with custom pin configurations made just for me... My top pin is .29, whle the remaining three are .19s.. I've thought about getting the bottom pin in .10, but that's just getting too small for my 40-year-old eyes.

I've found .29 to be perfect for 20-yard shots and in... You've got to realize how much target you'll be able to see (assuming whitetails here) at that distance, and if it's a wrapped pin like on the Spot Hoggs, it'll really be visible until probably after legal shooting light.
