About a year ago I kinda pissed James Hallows off saying that Cougar pots will be crap. After calling me uneducated and so, he stated that Cougar pots will be infinitely better than ones in F22, completely sealed (like that is gonna solve something, eh) and with greater resolution (this is matter of other hardware, not pot itself).
Just couple of days ago, he admitted his own Cougar missbehaves in pot department. So did few other people.
Right now, there is a kit for Cougar which uses HAL (magnetic contactless "pot") as with Simpeds, but it costs very much.
IMO, in a year from now, Cougar will be just another spiky F22 story. Sad. You just end up with spiky 300$ stick envying the kids who went Microsoft.
