Ha ha, 42 is bad altogether, yet there are some cars scooting around with 42 on their license plate. Funny, all the different superstitions in the world.
To answer your question, and this is what I did, since I didn't bother to ask advice when I bought mine. I got the 5k coz 1-5-8 doesn't seem to be as big of jump as 1-3-8 would be.
You could always do 1-3-5-8. Others may suggest
1-2-3-5-6-7-8-10,
but them people have serious HAD.
