Defensive fighting, short sword, trolls are your way to go. You get hella body control, mind speed and you train 2 skills at once. For the 1-50 skill grind use a 40-60ql shield with high coc and LT with your short sword. Aggressive fighting has a slight skill gain advantage over defensive but it is minimal. I went from 84.xx-90 shield skill in 8 hours of sleep bonus. I've gone from 1-50 skill in 3 hours of sleep bonus training large wooden shield. Also once your over 90ql shield skill keep your shield between 5-14ql quality, anything over 15 ql is butt cheek gains at that skill.
