tying the DS without line twist ... sorry, another DS question

new at it obviously, really think I need to get this into my arsenal,
and have read all the other threads on this and the various related
article, so allow some slack for maybe the obvious .....

I can't figure out how to eliminate the line twist, using the palomer
knot type, that happens when you taunt up the smaller dia. lines like
6lb test. had this problem as well when I was an avid fly fishermen with
the very fine leaders but that knot is at the end and if you get a
little twist, not as big a deal, plus it seems easier to pull it out
some at the end. I wet the line with saliva and try to take it slow, all
different ideas from the years I spend with fine leaders, but I always
get a pretty good curly cue in the line around the hook which I assume
isn't the best thing to have for efficiency. or maybe I'm too picky. any
tricks???

plus, one last thing. I here many guys talk about hook size, modeling
after RichZ, he suggests #2 Gamakatsu split shot/drop shot hooks, which
is a pretty small hook, or is that actually 2/0, which seems pretty big
to me.

like I said, probably the obvious, but just a little clarification would
be much appreciated. thanks in advance.
