Sorry, not very clear.
Duckster was correct, the lead dumbbell is tied in behind the HOOK eye...
As far as claw size goes, I've found that longer works better for me overall. Not likely to intimidate a smallmouth with a howitzer so I don't worry about it much. Largemouth will suck in and crush an 8 inch live craw with ease and I've caught some nice browns on these too, and they are also more agressive by nature. Maybe an issue with rainbows or other trout.
