Single dedicated line query

Still humming a hawing regarding utilization of a main-connected subpanel with multiple dedicated lines extending to outlets vs a single line from the main with 'pigtailed' outlets. Seem to be a pretty even split with some heavyweight opinions from both camps.

If I decided on a single line, for a 70 ft run from the main, I suspect at least 8 ga (6 ga?)wire should be used. If that is the case, is it practical (or possible) to direct that 8 ga on to the outlets? If not, what is the best method of stepping down to a smaller (say, 10 ga) size line?

A qualified electrician will be doing the work, and in fact once he began hearing of the idea of dedicated lines, asked me about this very issue. I just want to have a better grasp on what is best for my situation.

thanks

Your electrician will tell you that the correct wire size is 12ga. with a 20 amp circuit breaker.
It's not possible to expect to get 6 or 8ga. wire into a wall outlet box and then hook an outlet to it.
What you "suspect" should be used is one thing,the electrical code says what is the correct thing to use.
Also every time splices are made,wire sizes changed and pigtails used you are defeating the idea of a dedicated line. A saying in the trade says it all:
WIRING IS NOT A HOBBY. GET A PRO!
