If money was not a factor , I would select the Airmaster as first choice.
My personal story,
I had the 2 blade Sensenich ez pitch , a very nice prop.
I always read of a three blade prop being smoother and was intrigued by the three blade IVO GA and how it adjusted. A medium 3 blade ground adjustable came up for sale on barnstormers for a decent price so I bought it.
I liked how the GA IVO medium performed, but I knew there was the ability to make it an IFA, so it eventually was made into an IFA.
So far the best setup that I have had.
I would like to try the Airmaster with Whirlwind blades , but I can't justify the dollars to switch at this point.
Maybe one day ?
P.S. I put John McBean's advice very high and take it for being about the best there is.
