What I use is  Norman Speed Clips, They are available at Bass Pro, in I think three sizes. My guys at the club will probably crap when they see these. They aren't cheap, but are VERY strong.

Larry, That is the exact style that is on my Eagle Claw Micro Leaders.

Says they are offered from 30 to 100 lb sizes.


thanks, Robert

Sad to say Rod, they aren't safe for the fish!

John, I think most competent sporting goods stores will carry these. Also that big auction site has a number of these. Just do a search for " duolock snaps " and you can buy them by the hundred.
#1 or #2 would be best I think. #3 is for 40 lb test and would be OK but I would go for smaller if I could.

Do as I did when I was in doubt about the lines  for my carrier of years ago with electric throttle control.  I made up a really short set to test.  Scales hanging from the floor joices in the basement.  The lines hooked to a five gallon bucket.   Started adding wheel weights until the lines gave.  They surpassed the required maximum pull of 100 pounds that you have to pull if the plane weighs four pounds exactly.  Over four pounds the plane would not be allowed to fly.  I actually did tests twice, first was using the scissor clips which every body says is required.  The second test was with the old large Perfect slide clips.  Both tests went past the 100 pound pull. 

By the way the second test was with scales anchored to a chain from the floor joices so it would make so much racket when the bucket hit the floor.  Now if they pass pull test they should be legal, but, with law suits and such the AMA rules are to be met.  Have fun,  DOC Holliday
