One thing that you might wanna watch for that I've seen many traders do ... they hit cruise and then F1. When they hit F1 you cannot disrupt their cruise or their drift rate. They just keep floating off into the sunset.
So F1 while sitting still or at normal engine speed makes them vulnerable, they have learned this little trick of hitting F1 AFTER they enter cruise or at least a fast drift rate.
I've learned that the best way to counter this is when you see this happen ... cut your engines and stay stationary. Wait a little while and when they log back in ... you've got em where they started the cruise/F1. Then you get to watch them do it all over again.
