Hey Guys, Still saving for my new scope. Was looking to replace my Pentax Lightseeker XL 3x9x40 with a Viper PST. But the more I read on here the more confused I get. Seems that some of you guys are favoring the Sightron Glass over the PST. I like the features (bells and whistles) that the pst line offers but would appreciate the better glass more. My questions are: 1) Is the Sigtron SIII Glass that much better than the PST ? 2) How much better are either compared to the Pentax ? 3) Since must of my shooting/ hunting will be at 0 - 800yds(only steel and paper over 400yds) would I be better with the 4 x 16 or is the 6 x 25 to much at these ranges? Sorry for all the questions at once but dont get to set down at the computer much right now. Really enjoy and appreciate yalls input and experince on these topics. Thanks in Advance.
