Anyone ever figure out roughly the maximum pound leader you can use without cutting the Dink Float in half when trying to pull free from a snag?

Say I have 30lb power pro mainline with 20lb test leader. If the leader hangs on the bottom will it cut the Dink Float in half when I am trying to brake free from the snag.

I am using the good neoprene Dink Floats not the cheesy ones that look like backer rod material.
