Throwing your weight around

I might float the local river in my WaterMaster tomorrow .... just too
nice of weather to sit around. Once launched I'm stuck for a few
hours so I better be prepared for reality,

and reality is

nymphing will be the only likely way available to catch the
fishies. I'm thinking of taking a 10ft 5wt and 'high sticking'
the riffles and WBugging the frog water sections. I've heard a lot
about fishing with multiple nymphs but have never really tried it, a
single one beneath a dry is as close as I remember trying to deal with
multiple fly rigging.

My question ... what is the best ( defined as least prone to tangle )
way to rig a couple nymphs and maybe a split shot ... i.e. droppers,
all in a line hook bend to hook .... other? WHERE DO YOU put the
heaviest fly so that tangles are minimized ? ... last one, first
one ...other ?

Any ideas on cool fast and efficient ways to switch back and forth
from a riffle rig to a frog water one? ... besides a second rod
