line to leader connector

hi here is a dumb question. I just bought a pck of those scientific anglers L2L line to leader connectors. my fly line is 5 these ar supposed to be good for line up to 7 wt. I am having one heck of a time pushing this fly line up into this thing. anybody used these and how did you do it. This was suppossed to be very easy? help please

Griz;
are you using the tool provided? They are tough!! I’m looking at the new removable L2L connecter that JC featured here.


Don’t forget the Michigan Fish-In August 14th to the 20th. The Holy Water’s of the Au Sable await you!!

i didnt think you needed the tool for putting the fly line end threw. i will check the directions again.
