Which knot??

what knot(if any) would be recommended to tie two lines together of the same diametre(ultima distance 15lb, .35m). it wont be used for fishing, just practising casting. i dont really want to be filling a full new spool everytime i crack off while im trying to get the swing right.

cheers lads.

use a blood knot have a look in this link
look in the fishing section, no reason why you cant fish with joined line.

They say (uni to uni) reduces line strenght by 50% because the way the lines cross over each other.

Brilliant for links/swivels and hooks and the like

I am with MB3 on this one.
