Bob..IMO the 1.75to 6 doesn't offer enough of an upgrade to the 1,5to 5...but I'm a "little scope "guy!
As to the 1.5 to 5 Illum....I am old school..the more there is..the more there is to go wrong....Illum reticles fall into that category...and Murphy's Law is alive and well in Africa..
KISS principle applies..
and BTW toltegriz was exactly right on the lap top....
