What I have seen of the Arrow, it is a lovely traveller and not more or less problematic than other aircraft, if a bit on the thirsty side. I'd fly one any time, it did remind me a bit of the Senecas I flew before. It is still a very different animal to the fixed gear PA28's and rightly so. 20-30 kts more will demand some differences.
I have around 150 hours in Arrows and a dozen or so in the Seneca.
I reckon an Arrow is hard to beat in terms of speed/price/flyability/costs for the average private pilot.
If I could find an Arrow share for sale up here in sunny Northern Scotland, I'd buy it tomorrow.
