If you thought choosing a rifle would be confusing , the scope is much more important and will confuse you a lot more ,by all means look through as many scopes as you can,but you can't always discount a scope just by looking through it for 5 mins.
although going by what other people are using is a safe bet. If it isn't already being used on the hft circuit then its probably not suitable ,As with the guns most of us have been round the block trying lots of different scopes ,
just be aware its not always the scope with the biggest price tag that's best for your eyes .
The nail that sticks out gets hammered down.
