I was certainly never brave enough to try a loop in the Bucc - I was far too crap! We did a bit of tailchasing during my short struggle with the OCU course - and a lot of toss manoeuvres as well as tactical low level formation at which it was utterly superb.
For medium toss it was never necessary to get close to the vertical - and the excellent roll rate (second only to the Gnat!) was used to roll to over 90 deg AOB to pull down to the horizon to stop the climb, then a hard turn to escape. It formed part of the Buccaneer IRT in the Hunter T7A/T8B, if I recall correctly.
