Anyone familiar with clamshot weights?  They're a pinch-on, football shaped sinker.  I'm thinking they'd be great for split shotting but I don't have a clue as to what the sizes are.  Catalog lists them as #4 through #10.  Seems like the shape would slip through weeds better than a round split shot.  

I bought a bunch of them last year, thinking like you, that they would be good for weeds. Was I ever wrong. They will not stay centered on the line. And when they slip off-center, they will pick up more trash than normal shot. Try the water gremlin bull shot. They look like little bullet weights, and will stay centered on the line much better. I put all the clam shot in my panfish bag and just use them to balance floats. That's about all they're good for, in my opinion.

Cheers,

Thanks for the insight, maybe that's why they're not so popular.
