At the risk of repeating SC's points, and mine on other threads, Genna in the '52 would be my choice. I've only done 1 session with him (I'm not currently flying a 52) but learned so much.
To call the '52 'agricultural' is, IMHO, a tad unfair. It is certainly brick-built (it's a military aeroplane!) but it is beutifully engineered - far better than any western 'plane I've flown. It also handles superbly, with powerful, responsive, and well harmonised controls. 'Tis true it's thirsty, but then it has a mighty radial on the front which gives the sort of performance PPLs only dream of...
