Where are you going? I don't know that I would totally agree with your avoid list to be honest, except US. For example, UA would not be on my preferred list unless I was able to do a route that included their new C/F in which case it would not be so bad. OS, I am assuming you have them on your avoid list do to some older seats?? I have colleagues that fly them form IAD-VIE and are very happy with them. So, for me, it depends on the routes you are taking to say for sure.
F awards are easier in my opinion over the Atlantic as most people are happy with C/J and prefer to save the miles so I find F easier to obtain a lot of times.
