Cost Differential: I don’t know what an SR22 costs. I paid $350,173 for my fully-loaded C300 including an extra $5K because of the need for extra work to certify the first Canadian registered plane, and do my training in a factory rental. Is an SR22 a lot cheaper than that?
Well, I paid about $265K for my Sr22, but let’s compare apples to apples; acurrent SR22 vs a current C-350 with all the bells and whistles, de-ice, Skywatch, A/C, O2, etc.

Door safety: The Columbia has extremely positive and easy to latch doors. It had better - if a door opens in flight, it would depart the aircraft. Take a look at a Columbia door, it is easy to close and when it’s closed, you can be sure of it. Plus there are inflatable door seals. They reduce the noise in the cabin by a significant amount.
The door seals are wonderful and I wish I had them. What happens if the door departs the aircraft? Does it impact the tail?

Speed brakes: No one forces you to use them, but they do expand the envelope and provide options, which can only be a good thing. I tend to use them a lot near the destination during the very cold winter days. When a 3° glideslope with 1 notch of flaps and 90 knots would need 10" MP, I can do it with 13" with the brakes, keeping some CHT ready for a possible go around. I like to watch temperatures closely as you can see from my post here.
I always try to be gentle on the engine, but I am not sure that the CHT temp difference between a go around and your original take-off is significant reason to have an use speed brakes. I was kidding about most of that comment anyway! But being so cheap, I would hate to lose the built up energy (airspeed) by killing it with speed brakes. Realistically, I have never had an occaision where I wished that I had them, and if they were an option, I wouldn’t have paid for ‘em. OTOH, I suppose if I was on fire at 11,000’ the could be a lifesaver. [:$]

Airframe efficiency: Let’s call it the lift to drag ratio at a given airspeed. Where two planes of the same weight develop the same lift, the drag on the more efficient plane will be less, requiring less fuel, yielding a greater specific range. That’s a good thing.
Aren’t you just speaking about airspeed? I don’t care too much for the theoretical concepts, only how the plane works. The 300 is a few knots fster, but from what I’ve seen LOP the difference, if any is negligable. The effeciency is gained at the loss of a bit of comfort, but again the difference is not that great. The 300 has better range due to more fuel, but you can only use it a the cost of cabin load, but it is darn good to have the options.

Please don’t take any of this as negative, I really do appreciate the Cirri too. But I don’t have much time for folks who think a sensible buying decision can be made based on their perception of how easy it is to get into the back seat.
Steve, I don’t I respect you a lot, and a few of my comments have been tongue in cheek. Both planes are wonderful and worlds ahead of other competition, even as they struggle to catch up. The differences, primarily in nuances are great to talk about. BUT, I do check out back seats in the cars and planes that I buy. (Do you have kids?)
