the 3 size breaks at 30 psi.i tried it!!!it is small enough to embed in a plastic trick worm.if you use a hook like these http://www.basspro.com/webapp/wcs/stores/servlet/Product_10151_-1_10001_103724_100010002_100000000_100010000_100-10-2
you can t rig and hide the snap.it also sets the hook back furthur which i think works great.
