Prop Swap: Catto to Hartzell - What test data do you want?

[DHoover]

As the title says I'm swapping from a 3B Catto to a Hartzell in my RV-7. Thanks @Walt!

I'm waiting on my prop gov and cables to show up for the swap so I've got a little time yet and wondered if there's any specific test data folks would be interested in for this particular permutation of propellers?

Here's what I've considered so far:
- Measured change to CG (I'm too tail heavy currently)
- Takeoff performance
- Cruise performance by fuel flow, % Power, MP and RPM (I'd like to be able to judge blade efficiency knowing the Catto is really good)
- Measured Sound Level (my wife is an audiologist and I promised her it'd be quieter in cruise - hope I'm right)

I'll take any advice on testing these but what else would help folks choose props?
