Continued research of props and ignition on VAF and other websites. Talked to Nicole at Catto twice to learn more and then requested a quote. Researched whirlwind and requested a quote.
Had a very helpful phone call with an RV-7A builder at breakaway about Catto and electronic ignitions.
Was holding off on ordering an engine until I made a decision on the prop. Van's has a $1000 discount if you order a Lycoming engine and a Sensenich or Hartzell or MT Prop from them on the same day.
