I did a fair few golf bunkers years ago in the uk, on a nice little 802, it was the late 90's, I think you could safely say it took more experience to get the job done, lots of liitle things like keeping some spare material to get the machine sat on help get the angles etc, even with the tilty there is still is a fair bit of tracking to do initially if you want to have something evenly and well compacted thats not going to settle unevenly and be shite in a few years, I roughed some material round in a basic shape of the final pond, then tracked it in, did this a couple of times as i was digging inside but staying away from the final cuts, forming a rough version of it with excess material everywhere, then its simple with the tilty, you can sit in a couple of spots and shape it out of the rough version, that part of it was much trickier on a standard machine obviously, took lots of work positioning the machine to be able to cut the shape, id say we did some pretty nice work before but ultimately its a hell of a faff comparatively and taking waay more time/fuel/wear for similar results.
