There is a pretty big variety in meopta and zeiss lines IMO, some lighter, some clunkier. I will agree that the Optica5 and 6 lines are pretty ugly playing on the "tacticool" trend but i try not to let appearance overrule function. Meopta was actually the manufacturer of the original Zeiss Conquest line (rebadged meopta meopro and also same as the cabelas "euro" line) which probably sold more scopes than any of the conquest v4 or v6 lines currently available which are manufactured by Light optical works in Japan.
RE the rokslide reviews - what i've seen over the years is guys are really happy with the conquest v4 glass but have had some zero retention issues. The Optika6 scopes seem to have slightly more favorable reviews from the zero retention standpoint but it would be a big assumption whether or not that translates to the Optika5 line. I think either would be a nice option for a midwest hunting rifle.
