Vortex or Leupold? or something else?

[Whelenon]

Thinking of changing scopes. Heard a lot of good things about the Vortex Scopes. I have a Leupold 2.5-8X36(weight 11oz) on my Grendel, considering a Vortex 2.5-10X44(weight 18oz). Do you think this is a step-up? Weight is important so I don't think I want to go much bigger on glass.

Also, anyone have an extra Larue LT104 Scope Mount for sale?
