Do you have a pic of the head and hook? Then I can see what's going on...sometimes the barb of the hook can get in the way, but a little extra pressure (watch your fingers, its easy to poke them lol) can pop it over the barb. If the head will fit over the eye of the hook, the head is too big.
Ok, yea I'll snap a pic later tonight. The head basically gets stuck at the first bend of the hook when sliding it from the point of the hook going to the eye... I can get over the barb fine, but the head is just too wide to slide up that bend.
