Whirlwind GA200L vs Catto 3 blade

Well Known Member
I'm looking at changing my vintage 2005 Catto 3 blade prop for a Whirlwind GA200L ground adjustable.

The weight is about the same & I have been dealing with an aft cg. I am 20# light on the nose and others with this setup have added a steel spacer. I opted for weight on the inside firewall. But, since I'm looking at making a change, now is the time.

Is anyone doing this with the whirlwind to compensate?
Forget about it?

Any comments regarding the whirlwind would be appreciated.
