i believe that higher reps target the fast-twitch muscle fibers and less reps targets the slow-twitch muscle fibers or vis versa. Anyway, yes changing the amount of rep in a set would help you work the most amount of muscles in an area. Plus any change in a routine usually "shocks" your muscles into growing a little bit more. just my two cents, I could be wrong though.

For the first few years of training aim for low reps and heavy weight. Now at present its not unusual for me to do 25 rep sets. I think the ideal range is between 8-12. Experiment.
Ansew to the few pms I've gotten since popping back on-line...
NO I never got full amount back from 'him', still owed for FAKE t3 and wu fee... More than a year on I can't be bothered to carry on chasing it up.. Unfortunatly word is he is on another bb community forum still selling
For me when I work in the 8-12 rep range I have trouble progressing in weight for some reason. Doing three working sets of 5-8 reps has helped me greatly on all fronts. I think it's really just body dependent. The best anyone could tell you is shoot for six to twelve, mix it up once in awhile.
