That seems dangerous, I only use 12# mainline and a rig of 7" - 12" so that short piece of braid and a swivel is all that's left on the fish after a break. Perhaps if using a strong leader a weaker rig should be used. When I want to check for rig strength I just rig up as if for fishing, set the hook in the edge of the kitchen cupboard and walk backwards until it breaks. That will show you where your line will part if you get snagged.
