line to leader connection

like a little input please.  when using a noodle rod, or spinning gear, what type of connection works best for line to leader connection.  can i use micro swivels or should i use some kind of knot?

Actually just use the hook tied directly to line.  The fewer the knots, the less chance of knot failure. 

I like to tie a perfection loop in the end of the main line and leader and loop the two together.   Just seems like the strongest way to me. I haven't had the knot in the loop break yet.

I've been having trouble with leeches twisting up my line real bad on my flypole.  Never occured to me to use a swivel.  I haven't used a swivel in over 28 years but it looks like I'm gonna have to get some if I still want to use leechs as bait.  I've been growing monster leeches in the trunk of my car.  They are very easy to keep alive.

Rapala,
 
A micro swivel will work fine. Most people tend to make Steelheading far more complicated, and detail oriented than it needs to be, or is. VERY seldom do you need to go less than 6lb. test, I never do and consider myself to be fairly successful as a rule. The average angler using 4lb. or less tends to overplay ( potential fataly ) fish.
 
Spool your reel with you favorite line, and have at it, if you feel more comfortable with a flouro leader, again using a swivle to connect the two will be fine.

Rapala11,
    What you are saying is exactly what has plagued me for the last 4 years.  As the result of an injury, I have real trouble with my fine motor skills (lost some feeling in my arms, hands, and fingers so now when I hit the creek I already have a small snap swivel on my line and I carry coils of my favorite leader as I mentioned; which I have tied a knot loop on the end of.  That way when I get to the creek and my movements are further degraded by cold, fatigue, ect.  I can just snap on whatever end I think I will require.  I even carry an extra with a loop on one end and another snap swivel on the other in case I want to fish a flyrod lure on the end of my flyrod, with a long leader.  I can tie all the necessary lines up in the comfort of my chair.  Then I coil them and carry them in old leader baggies.  Not to be confused with lederhosen.  But you could have baggy lederhosen.  Hope this helps.

 
one more question concerning snaps.  i was planning on using a size 12 or 14.  they are pretty small. will they stand up to the run of a steelhead.  sure would hate to have them pull apart. 

i use a uni to uni for all line to line connections. some people say it doesnt hold up but i mainly use power pro with a flouro leader and it has yet to snap at the knot with some noteworthy smallies. critters of the toothy variety are a whole different story. best thing about it is if you tie it right you can cut the tag end back to the knot super close and it doesnt impede the casting distance a bit.
