T3s with STB backup as I suspect is the case with the majority of fanciers!!!! Not against ETS and can understand that if you race in a club with a small radius which specialises in sprint if one gets it all have to have one to compete. Me, I will wait for a bit until all systems have been tested and true prices of rings and accessories are clearer(some speculation that rings are currently being sold below true cost which will not always be the case!!!!).
