I generally only run a body brush over the saddle area, unless they are actually dirty, then quickly over the body. In summer I don't pick feet as there is never anything there - I can fell when I get on if they have a stone and they have never gotten one on dry ground. I pick out in winter.
I can be saddled in about 3 minutes but normally I take about 15.
I hog manes so nothing to brush and I don't touch tails unless they have been washed and conditioned.
I only do a full groom if i'm going to a show - The day before I wash, condition, groom and clean rugs.
My favourite product is Hi Shine Hot Oil - Fantastic stuff. It turned Bundy's big sunbleached patch into dapples and makes his tail shine like a mirror.
