I would look through both of them to see how it looks through your eyes. The sparc 2 you can have both eyes open, once mounted it may bring your cheek up higher on the shotgun which may or may not be a problem for you. Depending how far forward you mount on shotgun it may seem to have " tunnel vision". As far as the scope you did not list power but I'm sure it's a low power. I would not have it on greater than a 3x, if you do and the bird comes in close you will not get a good sight picture due to the magnification. Make sure the scope is a matt finish. The gloss reflects the sun and would give you away to both the turkeys and predators. Hope this helps and you get a nice bird this year!!!!!!
