Q for Spinn Twinn and similar users

I'm thinking of having an inner made for the Spinn Twinn. Would a 90 inch long net tent still allow sufficient front and rear overhang in the real world? I'd probably go with a solid back, and a lower half solid front for insurance. I believe the ridgeline is 117" and the wall length due to the cat cut is 101" (12" overhang in front, 6" in rear). I think I'd go about 50" in width.
