bublin, I do a similar style to that except I sat under the dryer for 30 minutes....Ill have to see how it turns out if I air dry it. My hair just seems to do better when indirect heat is used to dry it (less frizz, less shedding/breakage bc the cuticles are closed).
My other easy signature style I think Ive found is to wash, DC, and do a quick ponytail rollerset (6 ponytails with 1-2 rollers on each...I could do more or less rollers to vary the amount of curl)....take them out, fluff and go or put up in a loose updo. Its much quicker than a regular rollerset and requires less manipulation.
