Hope ya like leupold, as most guys running lightweights will use them. The 2.5-8x36 seem popular. I've got 2 on factory m700 mtn rifles and it's a nice set up but not really a fan.
Swarovski is a nicer option in the 3-9x36.
If your really worried about weight put your cartridges in your pocket and by bigger scope and your gun will weigh about the same!
