If you do get the GreenCult, also pick up one of the higher-numbered plates. Mine came with the II plate, but I got the III and IV plate in addition. I got the II plate because I was looking at the Blackbird originally, and the geometry of the II plate closely matches the reported geometry of the Blackbird. It does however look to me like it has much better blade support on the bottom than the Blackbird... Not sure what the effect of that is. I'm sure there are other differences too. Blackland suggests using the Blackbird at a shallow angle, and that's another reason I shied away from it, but plenty here say they use it with a steep angle with good success.
At first I thought the II plate was all I needed to get because I liked it so much (I was coming from a Timeless .95) but after trying the III and IV, I have to say I like the IV the best - and I'd skip the III if I had to do it again. You can shave much steeper with the IV plate and that's much kinder to my skin. I've also been shimming it to increase the gap and exposure. Up to 5 blade shims (I've only tried up to that) actually really increases the efficiency a lot and lets you shave at a really steep angle. It's actually completely changed my my thinking on what an ideal geometry would be for me.
