Congrats. It sounds like you have a solid list and you're getting very comfortable with it.
I know you're heavily invested in KoMT as stand-in so don't fret on this, but I had considered using RoR as the base for mounted Rangers. The lighter-armored models just seem more appropriate and I thought with a cloak to cover the obvious Rohan helm and perhaps a few other minor tweaks they would be good stand-ins.
I like your WotR list (can't confirm points at work I'm afraid). I was thinking a Gray Company / Army of the Dead combo when I wrap up my Rohan army (which I'm just starting...yeah...I plan way in advance
) and the Ranger part looks very similar to some of what you have below.
What have you mostly been facing with such a great track record? I am proud and confident in my play skill and army compositions but I usually only run about 75% - 80% wins in my local group based on my army, my opponents force and the scenario. That's a lot of games to maintain a zero-loss streak you have.
