I've caught quite a few this summer on lit docks at night at a resevior here in Texas (Cedar Creek). What I've seen is that small hooks work good, and also tandem hooks. They sometimes tend to short strike so a trailer hook can be a good idea. I still only get about 25% succesful hookups, but I have caught alot of other fish on my gar flies, so I cant afford not to have a hook on the fly.
