Everyone named so far are good choices. They all do tons of engines and have a lot of experience wringing the most out of them. You can’t really expect someone who only does a handful of them each season to be getting the maximum. You really need someone who does a ton and has tested and tweaked everything to the max.
All that said, driving is far more important at the rookie level. :)
