I've used the imp.clinch for years and still do for small dries/trout fishing,but I've been leaning towards the turle knot for my salmon fishing in recent years.I use a rapala loop knot for buggers and small streamers.

The Blood knot if defiantly the best for leader to leader or tippet.

Blood knots are definately neater,more in-line,transfer energy better and preferred for leader-leader knots/building hand tied leaders etc.,but double surgeon actually tests at a higher breaking strength for leader-tippet.
