Here is a Farseer on the new jetbike that I have converted. It's the same as the warlock and other jetbikes I have already made from Dark Eldar Reaver conversions.

I'm not even sure if this will be a valid option in the new Codex, but since we're not getting any new jetbikes with the new book, I've decided to go out in full force making all of my jetbikes like this. More to come at a later date once I have the codex picked up...
