Having completed my training at Stapleford and most of my hours building I would agree with littco and to save some hours prior to commencing CPL. I was introduced to my CPL instructor who guided me through my hours building and also prepared me for my CPL training by encouraging me to do some circuit details, general handling and good navigation technique BEFORE commencing my CPL rather than just burning hours and gaining lots of bad habits. I am very grateful for the experience as I finished my CPL training in minimum hours and with a first time pass.
