"JEKYLL Jr." 0.9 g,has a smaller silhouette of JEKYLL and a weaker water push. The situation where even JEKYLL does not eat is the turn of "Jr.". The standard hook is # 8, but if the fish are astringent, you can change it to # 6 to further reduce the appeal. I want to use it when there are fish but I don't eat them and I don't want to appeal as much as possible.Wide: 8.5mm ; Hook: # 8 ; Ring: # 0
