Is Leader Material Flouro different then main line flouro you buy in 300-600 yrd spools?

The other day i was on u-tube watching a knot video of a tournament angler, not sure if he was a pro.He is big on jig fishing, and uses braid and about 5 feet of flouro leader.He says he stopped using main line flouro as a leader, and is using leader material instead now"due to something put on the leader material that gives it better knot strength" (Yes his scientific answer). I just wonder if anybody else agrees with him, or if this is just his opinion? I always wondered why leader material cost so much.

I always thought that leader material was the original fluoro. Really stiff, but basically invisible underwater (or atleast my impression), and that main line fluoro was formulated with different crystals to be more castable, manageable etc, while the leader material is meant to be Ultra-invisible.

Someone correct me if im wrong though.

Like magic crystals? I guess to many Monster drinks?

Most companies use different resins in the leaders for abrasion and knot strength and leader material is stronger over shorter lengths.

What's wrong with what he said?  Fluorocarbon is a crystal and different blends create different characterisitcs. 

Dedicated fluorocarbon leader material is stiffer with a harder surface than casting fluorocarbon that has to be limper and more manageable.

It is usually sold in lengths that are used for saltwater fishing rigging. It is also packaged in loops a lot larger in diameter than casting line spools are due to the increased memory it has.

I guess i just got schooled by a 15 year old..Sorry Bassclary!

OUCH!

I use leader fluoro all the time, mostly Seaguar or Orvis Mirage. It's stiffer and stronger per diameter than regular main line fluoro. Tied to my main line of braid or fused superline as a leader, it's an awesome set up.

And yes, it's expensive as bleep. But folks are shelling out boocoo dinero for Tatsu, too.

My understanding of fluoro leader material is that kinks and acute bends weaken it significantly and a nail knot should be used to join it with a mainline.
