What's your intended purpose of the scope/rifle system? Picking a reticle is a lot dependent on what you plan on doing with the rifle. For PRS/shooting steel/even just plinking I will always recommend a basic tree style reticle. So, MR4 gets my choice 9 times out of 10. The open center dot is very nice as well. Now that I've shot with open center dot reticles I can't go back to a crosshair style reticle. The MR4 in my ZP5 is amazing. Nice and crisp, not too large but not too small. One of my favorite tree-style reticles to-date. The Vortex EBR7C and Kahles skmr3 are also some of my favorites.
