Mrs Wombat wouldn't be bothered by steep turns per se - we've been on a trip which involved steep turns over a glacier ('cos I'd just run out of film so the pilot said he'd hang around whilst I changed it and did a couple of orbits) between walls of rock.
Interesting, that. I'd always been taught to increase power for a steep turn, but this guy cut the power. On being questioned he explained that this was to keep the orbit within the space available between the cliffs on either side ...
