guess it really depends on how you want to fish - if i were doing a swing trip on those rivers, i'd fish a skagit or afs system with tips - the tips are 15' - which is more than enough - i see no reason why you'd need longer tips and running line. this of course assumes you're fishing a two handed rod and spey casting, where you definitely would NOT want the longer heads. i would start with the floater and intermediate and expect to have to go down deeper at some point.
if you're swinging with a one handed rod and overhead casting, then the longer tips may come in handy for casting purposes, but of course will make mending a little more difficult and i've never found them to be that helpful for swing fishing - they're great for salt and big water when you need to get seriously deep fast.
i'd leave the longer tips and running line at home - if you can cast the LC-13 tip across and down where you want it to go - you'll be fine...
as you know, there are a lot of ways to get a fly out there for the swing, and all flies look the same on the dangle
have fun
