I'm hoping someone can point me in the right direction as to what my issue is. I run 15-20 pound braid to an 8 pound flouro leader on my spinning rod and never have an issue. I use an Alberto knot with 7 wraps up and 7-8 wraps down. I want to use 40 pound braid to a 17-20 pound flouro or mono leader, but I keep having issues with the knot coming loose. I'm using the same Alberto knot and the same 7 wraps up and 7-8 wraps down. I'm leaving about an 1/8 to 1/4 inch of tag end on my braid and am cutting my mono/flouro tag end tight to the knot. I'm really tugging on the knot to make sure it's tight before I cut my tag ends. Any idea what I'm doing wrong that it's coming undone? It does seem to hold for a little while (probably 25-50 casts). I lost a Magdraft a couple weeks ago and would have lost another bait last week but fortunately I checked the knot before a cast and when I tested it by pulling on the lines, it came apart, so I just gave up on running a leader and went straight braid. I also lost a Spro KGB Chad Shad last year due to a connection knot failure as well, so this has cost me a good chunk of money already. If I can't get it figured out I'm just going to run straight braid, but there are definitely times where I want to run a leader if I can. Any help would be appreciated.
