Since I'm not prepared to do it I'll pass on what I would like to see in
the way of an evaluation. My first observation is that is issue is not
the loss in RG-174u itself but rather the relative losses between the
various choices. For analysis purposes I'd restrict the universe to
dipoles cut to length for the band of choice. As most use 20m and 7m I'd
focus on those first. This is not to say other bands and antennas are not
good choice just to focus the discussion.

So what I'd like to see is the losses on 20 and 40 for a dipole fed with

1. RG 8x
2. RG-174u
3. 300 ohm twin lead - including the losses from the tuner. I'd use the
ZM-2 for this as that seems to be what most are using.

I would do this for both 20 ft and 50 ft coax - twin lead.

Then all we would need is the weight of the three systems - tuner, lead,
and ant to make a choice.

Does some one want to put this together. The only information we all
don't have easy access to is the losses in the tuner.
