ortho camera and...

quick question. I noticed in tutorials nobody is ever zooming in and out everytime they switch ortho while boxing or edge modeling. I also read in the manual that zoomin in and out can also change your increments when extruding as well.

does anybody change their ortho viewport lens to say 65 so there zoomed way in? I also plan to start using snap to the grid as well since I wasn’t doing that before.

the last question is, I have the biggest issue with verticle placement. I don’t like box modeling but…I am finding strip,spline-cage or edge modeling I guess there, all the same, is my best bet. It only helps to a certain point though like face modeling.
I can do the head outline but when doing the cheeks for an example I have issues there. anybody have any recommendation or tutorials to watch?
