Thanks for the replys...Hi Crappie Pappy,I normally use alot of grubs rigged with round heads coming in with the hook from the front and when I first got the tubes to try I rigged them just like I do a grub.I got some of the jigheads made for going inside the tube to try(they are sixteenth ounce and have a size 4 hook)from BPS and I must be doing something wrong because I can't get them in.
