The 3.5" K Chub is based on the semi-oval Chub Grub body. While the tail itself is thin and moves easily, it is large with a wide base causing it to really displace water and cause a serious thump.
3" in the mold, 3.5" on the fall or swimming. The body is 1.75" long and .5" at it's widest. The tail is also 1.75" long.
