I use ERUPT & ADIOS. This gives all the vowels plus useful consonants. The other day this gave me all five letters so it was just a matter of sorting an anagram.
My first guess is always "trail".
Secondly, if I've only got a letter or 2, I'll then choose "chose".... see what I did there !!
Finally, again depending on how many letters I have, I'll choose "funky"
