Some players talk of using 3W from a certain lie of rough, and many of them might have a rewarding method, usually using the punch shot w/ top spin. I haven't mastered the proper yardage or total method yet, but I've been testing it out.
It all depends on the kind of shot and 3W (brand, level, ball, situation, % lie, technique, spin, etc.) Other players may simply not use it as a matter of preference.
3W punch from the rough
alanti's 3W punch from the rough -6th paragraph down " 3W punch from rough, depending on the lie - always think percentages, can be a great recovery shot"
3W from the rough but the replays are all expired. "3wd punch with top spin works from deep rough, for the Birdie"
