Good Question smile
Now if you think that there is a fish there---SET THE HOOK and then the next thing is SET THE HOOK again..even if its not a fish you will be glad that your settin the hook hard when it is a fish, accept with these silvers because they have softer mouths which mean a lighter hook set will do fine,
and as silver said maybe increase your led a litle bit or shorten your leader lenght so that its more direct tug from reel to hook...your hook size is plenty and the smaller the hook the less it weighs, thus making it snag less. Just make sure that they are as sharp as possible!!!
Also if you are really having troubles maybe try addin a bobber, they are a great way to learn how to detect bites or hits/strikes.

Now get out there and put the smack down on some fish~~~~!!!!
