I'm pro core and classic, but for now I'm throwing my chips on classic. I've fired up a Classic node and turned on all of my old mining HW to Slush to vote in favour of the HF.
If the HF destroys Bitcoin, then so be it.
Pretty reckless to risk your investment (and Bitcoin protocol) to fix the non-existent problem of full blocks.
Some would say allowing a company to capture the protocol, steer it to their will, while selling lackeys on the idea that it is all in the name of safety and decentralization... would be pretty reckless. I guess it's all a matter of perspective.
