Here is a link to a good video about twitching. Keep in mind the videos talking about trout....but the method is the same. You let the lure fall to the depth you think the Gills are at and start twitching. If you saw my post today about Normandy I used the twitch method to catch the trout....and also the rock bass. You may want to put a size "B" split shot 18 inches above the TM if it is windy. Let me know if you have anymore questions.
