IMO not wanting the credit cards cancelled if you had someone manage your money is simply nothing but an excuse to keep all of your credit cards. I would cancel all of them, since you are playing with fire having them, and get yourself one credit card with a low spending limit. I have one with a $1000 spending limit. An even safer approach would be to get these prepaid cards. The ones that I know of are backed by VISA, so they would be a good substitute for a credit card. FWIW
