I actually agree that a top turn (throwing buckets) usually looks better when frontside but you started by talking about bottom turns and getting vertical and IMO you are then better off backside for the same reason i.e. you can lean back and put your full weight into it whilst supported by the kite as in your picture.
Assuming there is a bit of onshore in the wind like we usually get here that is.
Frontside, backside, hooked, unhooked who cares do what feels good.
