I prefer, and recommend, the Jepp/ASA CR types. Some ATPL questions can be solved with fewer steps than when using a CRP type. They also avoid the iterative process involved with 'wind down' technique for HDG/GS questions. And the two smaller models fit in your pocket when you're finished with them. Trouble is UK instructors who nay say them without ever having even held one.
