I have done a lot of research on ignition systems and I am leaning heavily towards the SDS EFI electronic ignition (specifically the dual ECU EM-5 6F with the CPI-2 programmer). If I go with the SDS system, I will also likely go with the AS Flightlines hose assemblies that are specifically made for this system. Using these hoses makes things a whole lot more plug and play with good instructions that describe the necessary modifications.
