Well, I feel that the only way to recognise it is by looking at the HSI.
You mean the AI or the TC, presumably? Spotting a roll on the HSI is going to take a good while longer
I just think the SR22 deserves the description of "being slippery". But a decent pilot will be able to master it and then it is a great aircraft. A bit like a thoroughbred racehorse: not everyone can ride one, but if you can. they're FAST!
I think this is being over-cooked. I fly a TB20 which is of similar performance to the SR22 and while it is obviously quicker than a C152, enroute the difference is meaningless other than one arrives 1/3 sooner.
I think the main difference between flying at 100kt and flying at 150kt is that in a 100kt plane you can arrive at the destination circuit and just join in, whereas if you are going at 150kt you need to slow down quite a bit, and you can't do that if you are descending at the same time, so one needs to think ahead a lot more in the arrival phase.
I fly a few types and the SR22 is more likely to give me 30 degrees of bank without my sensing it than any other aircraft I fly.
I think that may be because of the SR22 side sticks being easy to over-control. I have flown in an SR22 once or twice and found it pretty difficult to control the roll as precisely as one can easily do with a yoke. One needs to use the aileron trim a lot and I think most pilots just use the autopilot the whole time. I prefer the yoke but the side stick is clearly a better long range touring setup than a centre stick.
