This will also be helpful for other trade skills. If the title was not enough of a hook then I am sorry you did not come here to read that which may help with other trade skills.

Using the /outputfile command in game do your command for what ever trade you may be working on for example /outputfile recipes fletching. Select your file from where it was saved and upload it to the parser.
Buy the books that are listed. Buy all the books that aren't listed. Go nuts and scribe all the trade skill recipe books you can find. Some books will become visible on the vendors after you have raised your skill enough.
Filter though that list with the quick trivial list for whatever trade skill from EQTC. If that parser has a way to load trivial recipe numbers then it will be as if the heavens opened and the sun decided to shine upon you. I have no idea if it can show trivial numbers for the recipes.
Do it as if you were already pursuing a skill level of 350 with all the alternate advancement abilities done and out of the way.
Be angry that there are some recipes sets that should probably have some books to scribe. This part is unavoidable and aggravating.
Make every bit of furniture, every bow, every type of arrow that you can and do have the materials for except...Karana only recipes.
I made zero of the Karana recipes. I started to at one point and made some steel fletching. Once I priced the steel ore and compared it to the similar items in Wood elf fletching I said 'By the fires of Ro this will not be done!'
There are 36 different Bazu bone bows so I still have some work to do for that 350 skill. After doing everything else though and still having some arrows to work on and still not doing a thousands of one type of arrow I was able to get my halfling his fletcher's arrow. AT the end I was able to finish it off with velium infused logs. All trivials over 335 give the same amount of exp to the trophy.
