For years my very favorite plastic craw was the Guido bug, made famous by Guido and Dion Hibdon. I used both sizes, the larger mostly fished alone Texas rigged and the baby Guido Bug as a jig trailer or fished on a Texas rig or shakey head. It was an excellent bait for me through the years. I've finally used up most all of my supply. I've found a close replica with the Zoom critter craw. The back of the old Guido bug was smooth, and the critter craw has some ribs on the tail section. What I always liked about the Baby Guido bug was the long antennas and the overall shape of these baits. I've tried other plastic craw baits with larger flapping craws, and small antennas and they never seemed to work quite as good. Two examples are the Larew salt craw and the Paca chunk baits. I know lots of folks do well with these, but I've not done as well with them.If I was using a black jig with a Guido bug, it was easy to change trailer color- black/blue, black/red claw, or black chartreuse, which would sometimes trigger a strike.Maybe at times, craw baits don't need to be very realistic, and only mimic the general shape and size of the crawfish in your waters. But, I think it pays to sweat the details, with shape, antannaes, craw size and colors. Now, there are so many craw baits out there. What do you look for in a soft crawfish bait, and what are some of your favorites?
