Weights over 10000 ft

[tundramonkey]

What size weights are you guys running in a M7 162 over 10kft?

Have cutler adjustables 65-75 grams. Was running them empty on my trip to the snowies and was only able to pull 73-7400 rpm. Secondary has orange spring and a gold in the primary.

Thanks

63 seems to be a good spot if you have the orange secondary
