Welcome, nice to have another 2.35 10ft guy on the boards.
I used to have m60's and currently have m80's. My first row of seating is 3 lazy boy recliners. I also have a stage below my screen, but am not using an AT screen. My front wall is 15ft wide so my speakers are to the left/right of the screen.
When seated in the front row, the tweeters of my 80's pretty much are at ear level, maybe slighly higher. The VP150 is mounted right below the lower edge of the screen and tilted slighly upward.
In regards to toe-in, so far I've found the best results by having my 80's (or 60's) aimed just behind the head of the person sitting in the middle recliner. When seated it looks like the side of my 80's closest to the screen is just skimming past to cooresponding ear.
The front row is about 13ft or so back and I have my 80's spread out about 12ft or so.
