Dear users of the Vortex Razor HD 5-20x50 (gen 1 or 2)...think its worth upgrading my EBR-1 reticle to the EBR-2? Vortex will do it for $300 and not sure if its worth doing or not. I like windage holdovers for follow up shots in wind at distance. Anyone have experience with the EBR-2 or both? Thanks in advance. Jesse
