I'd have your sinker sliding though and not your hook...for eds, that way when they pick you up they do not feel the sinker mass and can take off. I fish livebait throwbaits like this as well baits as for grunter and the likes. I find the three ways you loose a bit of bite sensitivity compared to the 2ways from all the potential movement in the swivel, in situations where large fish are going to take you down and not bite this does not matter and can be advantageous, for scratching it sucks as you don't know what is happening on the other end of the line. Otherwise normally I attach hookline to one end and mainline and sinker line to the other end of a two way and that works for me..
Lately when scratching I've just been fishing with variations on a "charter special" trace that my mate showed me, no swivel to spook fish when the water is clear or fish are fussy. This has thus far got me my PB kollie, wildeperd and gallie so can't fault it. Double uni to uni and mainline tag as hook line and .40 etc for sinker line which is on the tag of that knot, this for light scratching and alternatively scratching where cracker might pick you up, a .7mm uni-uni to your mainline doubled in a big loop, trim tags, hook link is .7mm tag and cut one end of mainline loop tag and attach your sinker to that with a granny knot above sinker so break off there when you get stuck. I'm still on a steep learning curve..
