STD if those are the only two scopes you are sold on then save yourself some money and buy the VXIII. The LPS is a fine scope don't get me wrong, BUT despite it's 30mm tube there is still 1" glass inside it! I just don't think they are worth the couple hundred extra compared too the VXIII series. For the same money you can get into the 1" Swarovski AV series and they ARE clearer than either the Luepolds. I have a 3.5x10x50 VariXIII and a 4.5x14x50 VariXIII and when talking about reaching out and touching someone with mil-dots you will want the most magnification you can get. In all honesty a 10x isn't really any different than a 9. At least with a 14 you can draw down on them. Is this going to be a treestand rifle or one you are going to tote? If it will be primarily used while stationary you might wanna look at the 6x20x50 Leupold. My brother has one on his 300WSM Abolt and though he primarily uses it for treestandin, it worked great on our mulie/lope hunt in WY lastyear. He has the mildot reticle and ANYTHING within 600yds is "goin for a ride in the truck" On that same hunt I had my 6x24x50 Swarovski PVS atop my Sako Warbird and it too performed flawlessly but our closest shots were 125yds on mulies and both lopes were shot over 300.

Good luck,

ps
My opinion of THE most perfect scope? If Swarovski would build a <15" scope that weighed under 1# and had the range of 4x30 with a 56mm bell on a 30mm tube with their TDS Plex reticle and could do it for less than $2k-3k I'd be ALLOVER it!
