My August Challenge so far.

I have fished two ponds in the past week. My challenge is to fish with a t-rig in pumpin color. I am getting a good feel for the bottom, and I have caught a few fish, two bass one on a zoom lizard and one on a senko. A couple of bluegills and a crappie on a zoom fluke. I just am not having the luck that I thought I would. The two bass I caught maybe equal a pound and a half to two.  I have heard that senkos would just plain out catch fish, but I am not having those results. I am dragging the bait across the bottom. All of the fish I have caught have come within 3-5ft of the bank. I was really suprised that the bluegill and crappie would hit a 4/0 hook. I am getting frustrated that I can catch fish by structure, when I can see them. Any suggestions as to what I can do different. Thanks
