I wouldn't think there's much difference. I've had a few airplanes in
ice, but not a Bonanaza. It's hard to quantify since each accretion is
unique. I've been in a 172 in fairly bad ice, IMC and completely lost my
ability to hold alitutde in just a few seconds. I was fairly high. 9,000
maybe? it was pretty warm below and I told ATC I needed descent and
needed it now. they said "we'l have it for you shortly", and I had to
reply that it didn't matter, I was coming down anyway at that stage.
I've flown Mooneys in ice and they seem to be better at just plain not
picking it up than most airplanes. Again, hard to quantify, I could just
possibly have been lucky with the conditions. Cessna singles seem to
suffer worst with is. Struts, long gear legs and what not, I guess. It's
a complete non-event in jets, though. Most types rarely even get
airframe icing and even if they do the hot wings blos it off quickly.
The engines are more of a worry, but the anti-ice on them works well.

I don't plan on trying it in the Bonanza -- at least not this A36 and
certainly not the straight 35..

There are a few out there with TKS and other systems, but it seems if
you have that need you should be flying a twin or a turboprop, not a
normally aspirated Bonanza.

I haven't flown a 172 that I would want to fly any length of time in
IMC -- you're in it too long as you're so slow, the big wing catches
every bump, and the climb performance is anemic (unless you have the
180 HP conversion).
