Cheers Rob,
I have read that thread as well. Part of the reason I wanted to pose the question. They are still 2 singles, rather than a proper 'double' hook.
Double hooks like the ones on Yo-Zuri Bonitas etc. Thicker gauge wire, closer together points than a treble, but still more points than just the single.
The only downside I can see would be harder to penetrate the mouth of a fish, but then the same problem is evident in trebles anyway
Thoughts?
Cheers
Ben
