On the matrix side of the dark horse I know that the opening is adjustable. What is the tallest you can make it.  I have never shot a bow out of a blind before I wanna make sure That I have plenty of romm to shoot out of or I will have to keep looking for a blind with bigger shooting windows.

It opens wider than you will want it to for deer hunting. It adjusts from 1 to 23 inches. I closed mine more than half-way when practicing the other day. Anyway, there is plenty of room for shooting.

You will have no problems in regards to window size. They adjust plenty wide.

I just bought mine and it's great. You might want to get the QS3 tri-stool. It's made for the blind. I had to shoot on my knee's because my chair was to tall. Got my black tail second day in the blind.
