congor rig

Hi all, so far I have only been catching congor up to about a metre long but have lost some quite a bit bigger, admitedly only using 50lb snood line, tried using wire but haven't had as many takes, this seems to be a common experience from what I read here so I'm going back to mono this time uprated to 150lb, it's pretty thick should I be tieing on hooks and swivels or using crimps like on the wire

What mainline strength are you using? Lost more eels to this breaking rather than the actual biting trace going or being bitten through

use 30lb reel line and a 80lb shockleader if ur fishing into rocks and for the trase
use a really good not if u can or crimps are ok if u do them rite

thanks, I normally fish off rocks or pier walls for them using a boat rod with 30 line, all lost ells have been due to the light snood line being bitten through, it would come back with the last few inches badly scored/scraped
