Bonanza (A36) Approach Speeds

I have an S35. Eckelbar reccommends 15-16 inches and whatever RPM you
had it at in cruise, 2100-2500. I get 135-140 MPH indicated and fly the
approaches at that speed. At the outer marker/FAF/inbound course
intercept I'll lower the gear. That by itself tips the nose over to
about 500 fpm, and slows you down about 20 mph, just what you need for
the ILS. Fly the rest of the approach at about 110 MPH indicated. No
need for flaps until short final if you want them, otherwise don't
bother. As you pull more power out it slows down nicely.
Thanks.
That's pretty much what I've been doing to date -- slow to 105 prior
to FAF, drop gear at FAF, re-trim to maintain 105, descend at 550-600
FPM (depending on headwind).
The only I problem I see with this method is that once the runway is
in sight, there's a significant configuration change to slow the
airplane down and still remain on glideslope while getting to a more
appropriate approach speed (The A36 POH only specifies NORMAL LANDING
APPROACH SPEED).
The A36 lands in a very short space at 70 KIAS approach speed (power
is required to arrest the descent at that slow an airspeed). 78 KIAS
is recommended for power off emergency landing, so is probably the
best speed for short final.
I don't agree with the stereotypical Bonanza driver that lands at 100
KIAS and needs 4000 x 150 or greater. This wing will fly at a slow
enough speed to keep the landing roll short -- very short, in fact.
