REFLECTOR: CHTs and EGTs

[John Dibble]

I use my RMI (w/Franklin engine) exactly as you are planning.  The temps
do stay fairly consistent.  I would love to have all 6 cyl readings, but
I don't feel it's worth the effort to change.  If I was starting from
scratch, I would choose one with all 6 readings.
