I know that. My plan was to pay off the 8000, then transfer the available credit to the quicksilver and make that the 10k card, for example. Then I can use it and carry a balance if I want to and have zero interest. Or if they would let me, transfer the amount owed now- either way I would be reducing my credit line on the venture and increasing the credit line on my quicksilver. I was looking for thoughts on that. Assume for these purposes I plan to carry a balance and I also already redeemed the venture signup bonus 6 months ago.
