Many lenses; which too keep?

[Toralf Lund]

OK. I just subscribed to this list. Thought I might start by telling you 
about my most recent acquisition. I just bought an ME Super and a couple 
of lenses at a net auction, on a time of the year when not a lot of 
people care to place bids at such sites, I'm assuming, so the price was 
not very high...

Anyhow, I'll now have
   * A MZ-20 body
   * An ME Super body
   * A 28-80mm (power)zoom - you know, the one a lot of people seem to
     hate.
   * A 100-300mm zoom - not the one with the bad reviews this time, but
     the latest model; got it second hand a short while ago; it could
     hardly have been used at all.
   * A 70-210mm/4
   * An A-50/1.7
   * Another M or A 50/1.7
   * A 150mm/3.5
All the lenses are Pentax SMC.
So, any comments on this equipment? Also, I've actually considered 
selling some of the lenses, as they do overlap a bit, as you can see. 
That's if I can face the idea of parting with them... So, which ones do 
you reckon should go? One of the 50mms is an obvious candidate, and so 
is the 28-80 if I can get something else in the range, and I think I saw 
a used 35-80 in one of the local shops (would that be a better lens?), 
but how about the long zooms?
