Thanks for all of your help. I've been tying leaders using the traditional blood knot. About every third knot has been slipping. Not sure why (I don't have the blood knot tying tool), but I did an internet search and one person suggested using an Albright knot. Never heard of it before so I did a search on how to tie it. I have tied 4 leaders in the last 15 minutes using the Albright knot. For me the Albright knot is much easier to tie and it doesn't slip. I'm very happy with the results.
