Both 25-30 and 60Hz sets can use 60Hz, not other way around. You need a heavier core to use at 30Hz and possibly more turns. But go up in freqjencies and you have more reliable heavy part for free. Of course it's a back breaker.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
