As long as we're talking about propeller options, I think we're overlooking the GT blades for the V-530, which have been in use for several years on dozens of airplanes. The Aerostar factory furnishes them on new Yak-52s as an option (I think they said there was a recent order of 20). We have tested them on the Sukhoi SU-26M and Yak-52 with great results.

G'Day All,
I have been following the blog re the Whirlwind blades and note the email
from Eric re the GT Blades.
Please find the attached photo of my 18T at a Air Show performance.
Since fitting the GT blades, we have a shorter take off distance, a better
climb and cruise performance and as per Chris Sperou states, who is a Air
Display pilot of note in Australia and is cleared for aerobatics to 0 feet,
and has flown this aircraft with the old V-530 at Air Displays and states
that without a doubt, the performance with the GT blades
Is a huge improvement. Chris is of the opinion that it "hangs in" during the
manoeuvres far better than the V-530 Blades.
I have recently done a 2300nm round trip up north and I had absolutely no
bother getting in and out of short strips with full tanks, 3 people and
baggage.
I know of a Culp Special in Perth, Australia, that the owner has recently
fitted GT blades to the M14P and he clearly states that he has a better
performance and far less propeller turbulence from the propeller vortex
around the cockpit area.
So for my 2 bob I would have to say that what we are talking about with
regard to both props, is that they are both of a superior design and both
would offer a higher performance.
Here in Australia, the GT blades have proved to be superior in performance
on Yak 52, 18 and Yak 55 than the old V-530 blades. All round.
In fact, the GT blades fitted to the Australian manufactured Jabiru gives a
all round better performance than the original Jab blades.
This also applies to the rotax engine powered aircfat.
Cheers from Downsouth.
Chris

How much? What diameter is the prop with these blades? More or less than original? What are the overhaul hours/years on these blades? Are they legal to fit to EASA (restricted-)CoA certified Yak-18T? Thanks!
