Personal feeling is that you should be taught for the type you are flying - rather than for the licence you are seeking. During commercial training I was taught at one stage on a PA-28 with fixed gear that had a gear handle that we had to operate. Also we were expressly forbidden to use sideslipping on the c152 to knock off excess height because it was not a technique used commercially - the c152 sideslips excellently and might be very useful in an eng out situation. IMHO.
