I have a Zeiss 3x9-36,a 3x9 and 3x12 Swarovski and a Leupold Vari-x II 3x9-36 and have hunted with all on various rifles,BAR,Rem 700,Browning micro-medallion, and since becoming a Senior have settled on a Rem. Model Seven as my go to gun.It wears the Leupold.In the past I found the 3x12Swarovski too large.I loved the Zeiss but like the Swarovski the eye relief is too short making tree stand shooting difficult if I have to twist around to shoot rearward.It did make me proficient in "weak hand" shooting.I tried the Zeiss on the Model Seven but twice and finally went back to the Leupold.With the Leupold I have killed deer in as little light as you could hunt...and it was a lot less expensive.
