"Do you guy's think a 45 degree bank at full power & at 1500 feet AMSL with pax briefed about the turn is reckless?"
IMHO - no, not reckless.
What about a 40+ deg AOB, 360 deg turn (any where between 5 - 10 consecutive times) at 500ft.... is that reckless? I'd still have to say no.
However this is all dependent on level of pilot experience.
