You used my illustration of the white trick worm which has nothing to do with rigging a Senko.
The white trick worm ends up like my avatar (weedless wacky) with a 3/0 Gamakatsu Octopus hook #02413
If you use actual 5" Senkos like the chartueuse example, you do not have to heat the shrink tubing.
Most knock-offs don't have that diameter, so maybe you would want to shrink the tubing some.
#2 is the best for the most successful hook-ups.
