I'm also toying with this decision, but fortunately in = my case I=20 have
plenty of time to make up my mind. The thing that keeps = rattling=20 around
in my head is that the Cozy I'm building was really = intended to fly=20
high. I see pilots talking about exactly what altitude they start = their=20
oxygen, and it adds fuel to my turbo fire.

What I haven't = been able=20 to quantify is exactly how beneficial the turbo
is in this case -=20 normalization. It seems you can calculate the numbers
to support = either=20 argument, and you have to weigh your goals against the
pros and = cons of=20 either decision. Sometimes choice is a bad thing.

I guess, in = the end,=20 I will probably install a T04 mainly because I'm
following closely = in John=20 Slade's footsteps, and so far his T04 is
working out. I have = enough time=20 to watch how it continues to perform as
he builds up more hours on = it. So=20 far it seems promising. Eyes and minds
open, I=20 guess.
