I have found that if you use mono and fluoro, you might want to try your own tests. I have found that I needed a different knot depending on what was being connected to what. I had one knot cut very fast. My results will not be of any value for you,other than to strongly suggest that you actually try the surgeons and the blood knot with whatever 'combo' you are using. Remember, all leader and tippet have different characteristics; strength, abrasion resistance, etc. Only you can make the best choice. "Tie 'em & try 'em," thats what Castwell says!
