Senko's

I haven't posted hear for a long time, and I think that's why I have
been sucking in my tournaments lately. I fish Senko type baits alot and
they just don't seem to be catching the fish they did a few years back,
I fish them mostly Texas rig and whacky some, could I be fishing the
baits too fast? I have a tournament this Sunday and the lake is kinda
stained water, what color, size and technique do you guys think I should
use or should I just try a different bait.
