I used the trust route for my things. The first time I went the individual route and the CLEO messed up his part. I didn't find out about it until 4 months later when the ATF sent me a letter. I decided to go the trust route after that to eliminate any other mistakes.
You still have to file a citizenship/verification form(s), but you do away with the finger print cards and the CLEO signiture.
Good luck with your paperwork
BTW-I used Quicken Willmaker.
If you do go the Trust route, send in your entire Trust document minus the instructions. It will save you the heartache of getting a return letter and the longer wait.
