I've just taken my lamb out of the slow cooker having tried a peice and it is absolutely perfectly cooked .. pleased so far !! 
An observation only at this stage .. the base I cooked the lamb in tastes divine but does seem to have
1. Lost quite a lot of the 'curry' flavour it had previous to slow cooking ,
2. The base consistency has changed from 'runny wallpaper paste' to a 'milky' consistency which makes me wonder if I should reduce it down a little to restore it's original thickness.
I'm cooking 'Curry King's' lamb bhuna tonight so an answer to the reduction would be nice PDQ please
