Saw these at Fall In, and they are indeed nice figures. I will be backing as soon as I've sorted out my finances. The unfortunate part of the flexible funding is that they collect it right away. Unlike KS where you have up to seven days after the close of the campaign to pay.
I think it makes a significant strategic difference. Under the typical KS I would have already backed it and other backers would see that. The current way I cannot indicate my support until I have the funds. Who know, there may be a dozen or more people who could already be backers but are "waiting for payday", etc.
