Flying out of Jersey to both the UK and France I'd say:
99% radar vectored ILS - with a couple of DME arc to ILS procedural approaches (Waterford and La Rochelle) and a couple of NDP at Shoreham (with the 530 configured up using OBS mode)
En route all done with GPS - in France and Europe lots of directs provided to waypoints many many miles distant to cut legs (IO540 has some great writeups on his site about this).
Not many holds in real world flying, but would probably say 3 or 4 a year.
Most of the holds and procedural approaches and non-precision approaches generally done when going up for some refresher flying or in revalidation flights.
