Interesting stuff bob p, numbers on lures just example 1 and 2. Total length only about 1 and 1/4 inch, total exposed-about 3 quarter inch.. I use these on shallow trolling lures....I've already tested them. I wondered if my theory of what i wanted to achieve with shape 2, as opposed to shape 1 seemed logical to others...It behaved as i hoped it would . Would like opinions of some of you guy's so as to affirm or not,what effect the change in action from1 to 2 would be ,if any...The other things that concerned me was as you mentioned i.e would number 2 be less forgiving in terms of bib build quality affecting action ,and also using method I use to make bibs would it be to tricky to produce. Regarding making them ,like many i cut on bandsaw then shape on disc sander. . Surprisingly actually not as difficult as imagined. Thanks again bob p.
