Ok, here is a very breif (but effective) guide. I have been doing this for a while now, and it really helps when skilling up a weapon and you don't know where to go. So, onto the guide.
Finding the job level
Ok, the first thing that you need to do is find the skill cap that you want to get up to (I suggest 30-40 higher then your current weapon is capped). For example, you have 105 skill, look for the level when you would cap at 140ish. Now, onto acctually how to do this.
First, go to http://www.ausystem.org/~aushacho/gbox/ff/skill-e.html and scroll down to when it lets you enter your job level. Keep entering levels around the range you think it should be at until you find the desired skill up level (E.G from above, finding at what level the weapon would have capped at 145.)
Finding the monster/s to skill off of
Now you know what level it would have capped at, you need to find what to kill. I am going to use the previous example in continuation here. At level 50, a warrior's great sword caps at around 147, our goal to get to from 105.
Now that we have this information, make your way over to
http://ffxi.cannotlinkto
and click on "Mobs" in the side pannel. When you are here, you will see "min level" and "max level". For the best results, I personally would use min level 48 max level 52, but thats just person prefernce.
There you have it, my breif guide to finding out what to skill up on. I hope you can find it helpful and helps you to get better, easier skill ups in future
