Hi hoot,
I have had different blinds but not the DB. I have been in a DB but I do not own one. That being said the material used in the DB was superior to that of my best blind the Ameristep Brickhouse.
The DB had the 360 viewable but i can also see in all directions out of my blind if i want to. However I always set up brushed in with the back windows closed so as not to get silhouetted.
With the Brickhouse I cut my lanes as anyone would using a treestand. There are times when you can shoot and times you can't. With the size of the windows in the brickhouse I have plenty of shooting lanes.
I'm not saying it is the best out there but I can say that for about $149 it has worked well.
As far as shooting through the mesh, I and anyone else can tell you it works or doesnt work but my sugestion would be to try it.
For me it works. At 20 and 30 yards I get no POI change using a Magnus Stinger broadhead. I practice out of my blind before season with no mesh then just before opener i verify the mesh is not changing the POI.
Good luck with your decision.
You don't have to have a DB but they are outstanding blinds made with quality material
