Thanks for the input. I'm leaning toward the straight. Although I'll use it more often at the range, convenience seems more critical in the field. I won't lose an opportunity because I have to stand up at the range. Since it's taken me this long to buy one, I know I won't buy both.
Slightly switching gears, I'm looking at the Bushnell 20-60x80 elite or the Nikon Sky and Earth in the same power range. Any preferences?
