Fly fishing leader?

[jlsch1]

Orvis use to be know zebco of fly fishing world.
Use to be beginners brand until moved something else.
Orvis line some products are good and others are ok.
Like older dxr fly reel and CFO reel made in England.
Rods they got nice ones and bad ones.

As far as loop to loop on leaders or line some mfg like Orvis and some cabelas brands fly lines and leaders have it.
If got loop to loop on fly line and leader quick way to change out leaders.
Put loop from leader over fly line and run tag end through fly line loop and pull straight.
You are now done tight lines.

If fly line don't have loop knot the best way to attach leader is cut off loop.
Then attach with nail knot.
