"O/U are great for the reason you've stated... they tend to swing faster and you can choke the barrels with 2 different chokes, one for those close up shots and one for the shots that are a little further out."

That could be a real advantage for turkey. Put a super-tight turkey choke on one side, a regular full on the other. Turkey chokes are so tight that if the bird is too close, you won't get much of a pattern at all.

I agree the camo is not necessary, but I tape my 870 for turkey hunting -- just makes me feel better.

Good luck.
