I don't have them, but I have a friend that threw both last week (drilled the same). Here is my take on them. Green Mamba has more backend and is stronger. Hybrid Mamba, is smoother and a bit longer than the Green Mamba. I definitely see the Hybrid as a step down from the Green Mamba. Personally, I liked both, but for me I liked the Mamba Hybrid overall due to its smoother controlled reaction. Hope this helps out.
