Thanks for your thoughts, Frank! (I'm not quite understanding the
"EDS
with composite tank" part of this though.)

Chris.

http://www.mhoxygen.com/ the EDS O2 system reduces your tank size by
a factor of 3 (http://www.mhoxygen.com/images/Duration-Chart.pdf) for
the same given amount of man hour usage over a standard constant flow
regulator, and a composite tank (carbon or kevlar wrapped aluminum
cylinder) is very light compared to a steel cylinder, but neither are
cheap, although it may be a cheaper option to install a $1200-$1500
oxy system in your plane you have rather than buying a new plane to
install around a cheaper oxy system.

If you have a forward hinged 1-35, by switching back to a removable
canopy, you will gain much usable cockpit load... I'm sure any 1-35
driver with a non-hinged canopy would be happy to trade. Of course
this is of no help if you are really just rationalizing buying a new
ship (which there is nothing wrong with of course, and incidentally no
cure for either- other than a new ship
