All In With The Best Hand

[Juff]

I'd push with 75% pot equity every opportunity I get in early-mid stages of a tournament if I knew it would get called every time.

Going all in with 75% pot equity 4 times in a row, you won't lose at least once; you'll lose ~68.5% of the time, meaning there's still an almost 1/3 chance of you having multiplied your chips by a factor of 16, putting you in great stead to take a stab at the top end of the payout structure.

Flushes are going to draw out on you; all you can do is make it -EV for the draws to call you. Letting the flush card hit for free/cheap is terrible, and you won't get paid when the draw misses.
