The poll doesn’t specify between SDS ignition only and SDS EFI. Yet EFII System 32 is a choice.
I currently have dual SDS CPI2 but would use the SDS EM-6 if doing it now.
I'd go with what I have on the RV-10. A mixed system - one mag,, one SDS. The SDS gives you mechanical reliability and a very flexible advance curve for performance. The mag gives you independence from an electrical system
I am building another airplane and unless something better comes along I’m going to install a SDS CPI 1. Light, inexpensive, maintenance free, and bulletproof.
