I haven' t any expierience with those you mentioned. So here is my suggestion. You are going to be in the open class if I' m not mistaken, because you' ll be using magnification. That is how it is around here anyway. So if that is the case, I recommend going to the adjustable sight/ scope direction. I' ve heard it called the " dial a guess" method.
Keep an eye out here for a used sightbar and scope.

I think you can get a Sureloc Challenger for around than $150 new. When I first got my target sight, I wanted a large scope lense and a choice of powers and pin options so I could find out what I' m comfortable with. I also wanted a good sightbar that is also affordable. I ended up with the Challenger and a GKF 3D Vision (2X,4X, and 6X lenses and green and orange fiber optics). I use it with a Super Peep with a yellow clarifier. It works great and I love the large field of view for 3D.
