i dont touch mine. i leave it bone stock which is now 4. and i run and gun. i very very rarely will not get those quick adjusters but it doesnt happen enough to make me raise it. i find that i even less rarely miss at range. and thats how i get alot of my kills. recognize and attack. i only play on a 34 inch flatscreen but it is literally 1 mabye 1 1/2 feet from my face, eye level. i find it absolutely imperative for your tv to be eye level. i just play so much better that way. so it all works excellent for me.
