its the mission!
Hairy plane
you have probably made the right decisions, but remember cirrus have an entry level plane at about £100K called the SRV
It really depends on the mission. Two weekends ago I dropped two friends to Toulouse. I left Booker at 0945 and was back 2 mins before they shut at 17:28 having flown 1114 nm in six and a half hours
I was completely relaxed and not tired after the two flights. It was done airliner style above the weather and IFR using the autopilot and all the facilities including my de-ice.
with 50 knot winds from the north fuel and flight times were hard to predict, but at all times while airborn my engine management systems were predicting accurate FOB and ETA s for every point in my flight plan.
If you need this kind of capability the SR22 really is the best value solution.
