Tippets are not graded by strength, but by diameter. By defination a 0x tippet is .011 inches in diameter. Each gradation of x is .001 difference, thus 6x is .005", and 3x is .008". There are also some #/0x definations around, and they work the same adding to tippet diameter, thus a 3/0x is .014".

Now, about the finest that one can draw monofilament is around .003" so a theoretical minimum tippet designation is 8x, but some manufacturers have stopped holding to the .001 defination, and are doing their own thing on tippets smaller than 7x.

Now, each size tippet from the same manufacturer is likely to break based on decending diameter, but across the sea of manufacturers tippets are not consistently breaking at the same tension.

And basically, fly fishing for trout has less to do with the breaking strength of the tippet, that the limpness of the tippet for a presentation. It is wholly inappropriate to fish a #20 griffith's gnat on a 2x tippet (you might not even get the tippet through the eye) as well as trying to cast a deer hair bass bug with a 5x tippet. One picks the tippet for the job.

Just get a range of tippets, 3x-6x work well for trout, 0x-3x is a good range for steelhead and bass, and use them proportional to hook size and conditions.

The short stiff leader for sinking flies is true, but one should take the species and their sensitivity into account. Basically, too long and limp a leader will not sink the fly with the line, when the line is a sinking line. This is when wanting a fly to drift along the bottom than drift at a middle depth.

With beadheads and body weighted flies the weight of the fly helps sink the fly so the leader can be longer and limper.

On a lake, it is better to fish a longer lighter leader as the fish can study the fly more than on a stream. And on the lake, if the line sinks faster than the fly, the fly will be drawn down by the line. It all depends on what you want, there are some circumstances when fishing a floating fly on a sinking line in a lake.
