I have to do a full recurrent every year and an LPC/OPC 6 months later on BOTH types, which is really a bit heavy since both aircraft I fly are with the same operator.... Luckily at least the line check counts for both types... The way we do it with double-rated pilots is that you go to the training centre twice a year, and do the long recurrent on one type, followed by a day OFF, followed by the LPC/OPC on the other type.
I still like the FAA system a lot better though...
