The eagle claw needless hooks go up to 5/0 in size. This is all I use for needless hooks. Make sure your using the right size hook. I just purchased the BPS Stik O Worm in the biggest diameter senko I have ever seen. Not opening the package to look at them before I left home I didn't have a bigger hook to use them. So I tried the biggest hook I had with me. You know what happened next right. As the stock o worm got close to shore were I could see it the biggest bass I have ever seen swam up and it had my worm in its mouth. A gallazion thoughts ran threw my mind in milliseconds. Do I dare try to set the hook? This is the new state record I been hunting for. Every time I catch other bass in this spot I been seeing bigger bass swim by me. Well I tried to set the hook and out the worm came. I didn't cry. My point if you never used senko' s and are new to them make sure your hook size I'd correct. This is a time when bigger is better.

I know I should of done my homework with this bigger worm first. Live and learn. Now I have every weedless hook that's known to man. This experience makes me fish harde

I used the standard senko hook on the super sized stick o worm and the bass won.

Gamma offers a weedless up to 6/0.

I like a Falcon K Wacky hook in the 3/0 size.  You can get them unweighted and in various weights.  I generally use the 1/16 oz weighted ones, cause I like the drop speed that I get with them more than the unweighted ones.  If I am using a weedless wacky hook on a senko, always use an O ring, rather than putting the hook through the bait.

I don't have much experience doing this, but have used the VMC Ike approved weedless wacky hooks and had great success.
