Nice work, hope it works out. This is the exact scope I'm looking at buying for my 6.5x47 - I like the Z3 lineup because of the weight, not to mention superb optics. Let us know how she fares!
Remember the BRH models are parallax corrected at 200m. Not a big deal, but when shooting groups at 100 yards be sure to keep your eye centered in the exit pupil.
Personally I'd keep it simple and light just like your rifle. Get a VX-2 either 4-12 or 3-9 either with a 40mm objective with the CDS to give you the option to tinker with dialing in ranges later, but they can be had for $300 or less. They hold zero, are waterproof, and plenty of good optics. A Leupy VX-2 has been on well over half the rifles I own and for good reason, for the price they are tough to beat. Plus they are the lightest in their class for sure. The VX-2 3-9X40 is roughly 11 or 12 oz. Main thing is don't weigh down your lightweight rifle with a 18 oz+ hubble scope thats for sure. I subsribed to the K.I.S.S. method when it comes to rifle scopes for sure.
