I tried the R22 thing as well. Was no better than the fixed wing option, you are always going to be bound by the weather and the UK has the most unreliable of weather going. Even with an IFR equipped helicopter which is multi engine territory in which case if you own or can operate one then you are not going to be flying yourself! You will be sat in the back with the other billionaires plotting the next world take over.
I have found IFR Airport to IFR airport passable.
