Personally, I like 4 the best as well. The main thing putting me off SPI2 is that we could do the work to set it up and then only sell 20k HIVE on the open market which is nothing into a 550k HIVE fund.
As said, i will leave them and see how im thinking in a few weeks. I'll update whatever i decide. Thank you as always to you and your father for the continued support 😎
