I have 3 Leupold VX-IIs...I like them, they hold zero, they track well, they are plenty bright to shoot during legal shooting hours...

I do have a couple of buddies that have had good luck with the Nikons in ProStaff and Buckmasters...

I have no use for a Simmons...Have a buddy that has returned his 3 times...They keep sending him a new one, we keep sighting in and tapping with a screwdrive to settle the cross hairs, it lasts about 2 years, loses its zeroand goes back again...
