I don't find BIFTs all that useful. How does "I don't like to bathe" or "I owe a debt I can't repay" going to give me any clue on their moral compass? Most of the time there's going to be little or no connection.
Some of them are okay, and the no bathing thing might be useful fluff, but I basically have to come up with a life history and then sort through dozens of entries or make my own to get something that will fit.
All for Joe the bartender and occasional informant.
So then I'd probably group some BIFTS together, give them an abbreviations and use those to give me a general idea. Probably come up with a handy 2 letter abbreviation.
