Hi Argo I agree. That is the way I work in the studios I use. It is pretty common practice throughout the industry to do three takes and cut them up to get the best bits. Most people tend to get bored, go stale, and lose the performance after three. You really can hear the difference.

After recording the three takes I listen to each take in turn sit with a b it papaer and clipboard and put ticks and crosses against each line on the three versions taking a note of any errors out of tune bits or parts I want to especially keep.
Funny thing is the vast majority of stuff used in the final mix always seems to come from the first version. It is just an odd line or word that comes from version two and hardly any from the third take.
