Fletching was my first. Back in '05 or '06. Back when fletching yew longs into (u) bows, and then stringing them, was MAJOR profit. I miss those days :'(
My first 99 was ranged. It's funny too, because that's by far my least favorite combat skill. I did aviansies 78-99 and made about 150M. Took like 2 months, but it was a huge accomplishment for me in the end.
