I understand why folks do this, especially after having some arcing 
problems in my tuner on 80m during the WPX contest (had to do an 
emergency cap repair on my output cap in the tuner - a plate had some 
serious meltdown!).  However, there are a couple of reasons why I like 
the concept of a tuner.  For one, it gives an additional layer of 
harmonic filtering.  Second, low pass filters are designed to have their 
lowpass response based on a 50 Ohm input and output and third, power 
meters are pretty much designed the same way.

So how do you get around this?  Having a power meter on a non-50 Ohm 
system probably isn't a big deal.  But I think it could be a big deal 
with the lowpass filter.  Or do you not run a lowpass filter and count on 
the harmonic suppression in the tank circuit to be good enough?  

73,
