There is nothing wrong with tying the Spectra lines to the connectors directly using Larkshead knots (Lenny Loops!), it works well.
I have started using welded rings (NOT split rings) at each end of the lines because it makes it pretty easy to just use regular clips for all of the hardpoint handles. Here's what I am doing:
I am using SPRO Power Welded Rings, several sizes are available, I like the #3.5 size rated at 266# I get them from Tackle Direct:

* First pix is of the welded ring. Its about a 5/32" ID, the wire about .015",
* After tying the Modified Surgeons Knot, you get two identical loops. Pass them trough the welded ring from opposite directions
* Slip some forceps through the loops and...
* Grab the welded ring with the forceps.
* Using the forceps, pull the welded ring back through the loops, you should see the Larkshead knot starting to form.
* SPIT ON IT, and pull it tight. I usually install these the last thing before doing the stretch/normalization on the lines; that is I pre-stretch the lines with the rings in place.
* You are left with a tidy little ring to pass a normal line clip through. Even if you tie the line clips at one end of the lines, this will make it real easy to use regular line clips at the other end to get your neutral setting. if you are using scissors style clips, like the Derrick Moran/Jim Lee clips the wire ring is physically a little larger and less likely to pass between the scissors.
