Anyone using these?

Largest you can get is a 2/0. Wish they came larger as my first two bites with this rig resulted in a missed fish as the gap is not deep enough for a  stick bait. They are however great with a Zoom trick worm which are much thinner either Wacky or Necko. Almost totally prevents line twist on spinning gear for me so far.

 

 

I watched a video on YouTube of Shin Fukae using them.  My understanding is he invented them.  I have been thinking about getting some of them.  There is an old mine quarry where I have permission to fish.  Lots of standing timber and brush piles.  But like you, I wonder if the bite gap is large enough for a stick bait.  Shin was using a 5" Senko as he was demonstrating rigging.    

Yep, I use it.  Great hook.  I made a few videos with Todd Faircloth using it.  Here's one of them:
