Trans choice questions.

I would go with the TH-350. Get the aluminum forward and direct drums (with HD sprag). If you can find a TH-250, they have a lightweight sun gear shell, gun drilled output shaft and front planetary that uses a roller bearing. TCI sells a low volume pump that is reasonably priced. If you have machine shop access, you can lighten up the output shaft and planetaries as well. Also, convert all thrust washers to needle thrust roller bearings. Another plus is installing clutch separators in low/reverse, second and high gear clutch packs, which cuts down on rotational drag. The higher you spin the motor, the more the lightweight stuff helps. Just my .02.
