Okay, for what you're looking for, I do what top hopper does. Here's a trick that will save you 75 cents: Top- a 16' piece of rope will give you a 9' lanyard. When you make the taper, the tail gets looooonger. So make your taper at the 7' mark, not the 8' mark. It'll start out crooked, but by the time you pull all those looong strands, the tail will be just about even with the body of the rope.
Jim- for the back splice, it's the same directions as a regular eye, you just cinch the eye down all the way. You can just to a direct bury with a tapered tail so that you don't have to mess around with the crossover, but it's a lot of work and maybe not worth it.
FWIW, I think the backsplice on the end of a lanyard is a great touch, and I wouldn't have it any other way on my own lanyard, but it does add a lot of $$ to an already expensive piece of gear for an eye that almost never gets used.
Finally, if you DO put an eye on the back, make sure you splice in a REAL eye on the back. I've seen people take shortcuts on the back end eye because they don't expect to be climbing on it. But one day you'll NEED to clip into that for some reason and you may or may not remember if it is or isn't strong enough to hold you.
If you wanted a stiffer line, only take out 9 or 8 strands instead of 10. This is what I do for my cambium savers and it lessens the likelyhood of them getting snagged on the way down. It would work here to make it easier to flip the rope up the tree/pole.
Feel free to ask any questions about this to clarify.
