Have to say I take the more relaxed methods mostly. and jump around between methods of levelling a fair bit to keep things interesting. I will often try to chose to make products with my production skills which could be useful to level other skills. I've certainly ranged a fair bit with my own smithed arrows over the years. Sitting their and calculating it all out before you start may be more efficient, it sounds duller though. After 7 years of play I have 1763 skill total (which is lower than most other people I know who have played since before members existed), but on the other hand at least I haven't got burnt out on level grind.
