I personaly think you are to late for the yo yos this year. We normaly wear them out in Febuary on yo yos but by mid March the water warms up enough for the gar to get active and you just cant keep the bait on them. I would say that you couldnt catch 10% of the fish on yo yos in April that you can in Jan and Feb. Thats my 2 cents worth.
Also peckerwood is pretty big and being down in the delta the wind can get to moving pretty good. I would definately want something with a gas motor if I was going to get on it. Unless you go early or late when the wind settles.
If you are wanting to fish with a tree limb in a couple of three weeks the limb line action on Ouachita should pick up. You bait 25 or so limb lines with big bream and you will get some big ole flat heads.
