You can not quick scope in Black Ops as quick as you could in Modern Warfare 2, but it is still possible. Try no-scoping. In my opinion, it's more enjoyable.
Yes! You can easily but isn't the same form of system like it is in MW. Black Ops has a challenging type of quickscoping with activision allowing a sway in the scope, it's the timing that matters on Black Ops.

No, there is no thermal scope in Black Ops but there is an Infared Scope very similar but players show white and the background is blue. This scope isn't called thermal scope, but it really is, they just changed the name.
Since you used the term "no scope" and not "hip fire," I'm assuming you're talking about a sniper rifle.

In Black Ops, due to the fact that quick scoping is now very hard, no scoping is now incredibly accurate.
You don't. The only available attachments for the G11 in Call of Duty: Black Ops are the Variable Zoom and the Low Power Scope.
