My advice? Use the acronyms that you were originally taught and, more importantly, learn them off by heart! You cannot afford to be pulling out checklists when you're joining the circuit or flying downwind - you have too many other things to look at and be doing. Personally I prefer the RAF way of doing things, ie. don't use any written checklists at all. It's very easy to memorise pre-startup checks and vital actions, and you are far more likely to skip a written check accidentally than you are to to miss a memorised check. As the RAF addage goes: "if it's there, check it; if it's not, don't."
As for the CRAP check, you've got enough to do on finals without introducing further pointless checks (after all, you're not flying an airliner). All this stuff should have been done before your turned finals. An examiner friend of mine was recently conducting an initial IR test, and the candidate insisted on doing a CRAP check - unfortunately, although he recited it word perfect, he hadn't actually received landing permission. Needless to say, he failed his IR.
