Old vert skater here, 41. skated 64mm back then, on 60mm now, for both cruising and vert. If your'e mainly concerned about skating ramps, which you probably were back then stick with the bigger wheels.
indy is new indy geometry, ace is old indy geometry.
skating a few decks ranging from 9.25 to 10, its not about balance, i just like more area to land on. but big wheels 58-60 are still the goto on transition. some go a bit smaller and have a do everything kinda setup.
6'0, 175lbs, athletic shape, 14.75" - 15" wheelbase fits great but not exactly stocked everywhere unless you go for the 'reissued' old school decks.
cant offer any advice if street skating is your thing.
