I think you could definitely have a play with a fibonacci on the side. Ultimately as has been proven on these forums before, even staking plans are effectively level stakes. As long as your method show a level stake profit, you can get away with a aggressive staking plan. In the end you will end up with an average sized bet, and as long as the SR and av divi are high, you should show a profit. Heres a few you could try, all rely on a $2.50 divi to break even, so any extra on the price is the "cream" on top

Obviously with those amounts you can divide them all to start with a much smaller bank. But you may want to run some of those over some past data and see how they go.
